- เผยแพร่เมื่อ 30 ก.ย. 2016
- A TH-cam viewer asked me to shoot a video on "Pipe Thread Sealant". At first, I thought it wouldn't be such a popular topic but after checking out some other You-Tube Videos I digress!
So in this video, I give you my thoughts and methods on the subject and in addition, feature some of the products I use in my everyday plumbing practice.
I'll leave links for the featured products below and as always you can reach me at info@bobsplumbingvideos.com. if you have any questions. Best Regards, Bob.

Just good ole common sense old school plumbing wisdom! Thank you!
Glad to help, thank for checking out the video!
Thanks so much for making this video! It was really helpful, clear, and detailed. Perfect for beginners like me.
Thank You for checking out the video! I appreciate it...Regards, Bob.
Thanks for the video. I only have to put a fitting on the end of hose with brass fittings on the ends, but now I know what to use. Hopefully the teflon will keep it from getting corroded together too.
Thanks so much! You took my small little job too another level. Simply I have to put a 90 Into my gas cook top. I was just going to use the gas teflon tape. I have two elbows to Install, going out to buy pipe dope. You rock!
I took apart my 74 year old utility(stone) sink, and the rope held up very well!
I’m training currently for maintenance in an apartment complex this definitely gives me some knowledge thank you 👍
Use it on any threaded seal connection. Drain pvc, drain brass, drain copper, iron natrural gas, etc. If its threaded...use some pipe thread sealant. Its not for sealing, its for anti-galling of threaded connections. Remember that. But that means sometimes you need it to get something tight enough to not leak. And without it you may have threads galling and not allowing full seating of your connection.
Great Video! I agree with you 100% use both Teflon and Dope! I’ve had multiple jobs with a small leak when my guys have just used one. Nothing more frustrating than to redo a job when it could have been solved with both
Beginner here, though I have replaced kitchen sink faucets. I'm about to tackle replacing my bath/shower faucet and this helped a lot! I did see thread hanging off the older pipes and was wondering what it was. Now I know!
Excellent video. Thanks for the detailed explanations. I wrestled with leaks installing an outdoor water spigot. Teflon tape alone didn't cut it. I ended up using Teflon tape and Real-Tuff Thread Sealant. Totally did the trick. Thanks much!
Thank Goodness Yo-yo Patrick for checking out the video! Regards, Bob.
I REALLY LOVE THE APPROACH AND DELIVERY IN PRESENTING YOUR CONTENT AND IS VERY EASY TO UNDERSTAND WHILE REASON AND DONE WITH NO MUSS OR FUSS WITH HIGH TREASURABILITY TO THOSE WHO PUT INTO ACTION. MANY THANKS AND BLESS YOU FROM BAD HAND, WEAK KNEED, AND SOLE REMAINING TO OLD FIXER UPPER AND ONLY KNOW WHAT MY DAD TAUGHT ME AND WATCHING MY GUARDIAN FATHER WHO WATCHES OVER ME NOW FOR MY DAD AND IS THE ONLY PLUMBER MY DAD WOULD USE WHEN NEEDED DONE AND NOW IS UP IN AGE TOO!
Excellent detailed educating video on sealing pipes. Thank you!!!
Thank you, Sir! Regards, Bob.
Very informative video! Helped me a lot to understand how I'll be installing equipment into a new pilot unit for my research project. Thank you Bob!
You're very welcome!
Best video I watched so far, answered all my questions
Much appreciated! Bob.
Excellent video, very informative. When I built my house about 30 years ago I hired a plumber friend to do the plumbing and I worked along with him. I had some experience sweating copper and working with PVC but by the time the house was finished I had experience with gas line installation, putting in a boiler, running a threading machine, codes, you name it. I think I could have become a plumbers apprentice. One thing he taught me that has stuck through the years is when allowed (not on gas pipe) to use Teflon tape and then pipe dope over it. He said doing this will just about guarantee you'll never have a leak and I never have so it was interesting to see that you do the same thing. The only time I ever had problems doing this was when I had to replace a leaking expansion tank on my boiler. The expansion tank is threaded into an air scoop which is made from thick cast iron. Teflon is a great lubricant and it allowed me to over tighten the expansion tank pretty easily and put a hair line crack in the scoop. I was told later by another plumber that he never uses Teflon tape on cast iron for just this reason, a lesson he learned the hard way himself.
Thank you Rich, much appreciated. Bob.
@@BobsPlumbingVideos what do you suggest on stainless to stainless or stainless to brass?
I am a new home owner and female who was never thought much about products to use. THank you for this video now I can teach my adult son.
Thank you very much for your great video, very informative, God bless you
Thank you for watching! Regards, Bob.
Thank you for making this video, answered all my questions. Very un-boring and helpful :)
Definitely learned from you about the pipe thread sealants. I am replacing a PRV. I put Teflon tape on the threads. The PRV is a brass fitting. The locknuts are brass from existing hardware on collar/tailpiece assembly. The bottom locknut seals. The top locknut is not completely flush, so the locknut does not bottom out correctly. Never used to paste before, but I am going to try it. If it works per a man of your experience, this is going to be a fun installation. This problem had me stumped. I lacked insight on the solution. It's a residential pressure reducing valve so I will set the psi at 60--65, but first I got to make sure the connections are water tight seal. Looking forward to plumbing.
Great video, my friend. Thank you for making it!
Thank you, my friend! My pleasure, thanks for checking it out. Regards, Bob.
I have had nothing but failures with teflon tape and struggled with leaking pipe joints for years. I thank you for exposing how to successfully sealing pipe thread fittings.
Long before Teflon, spool lampwick and Hercules pipe joint compound (Pro Dope) were the go too products. They worked when I was coming up in the trade and they’re bullet proof today! Thanks for checking out the video, regards. Bob.
Sounds like you were probably applying the teflon against the threads rather than with the threads(clockwise)
Great explanation on the different applications. You answered my specific question perfectly. Thank you.
Glad it was helpful! Bob
Thanks for the tips. I put in a new electric water heater and your videos were a great resource. I used Megaoc for the first time in combination with the teflon tape. Not a leak when I was finished.
Glad to help
Excellent. Cleared up some questions.. THanks!
You're welcome!
Thank you for this video. I will be installing a new boiler using black pipe for the supply and return headers. Your video was a great help in making sure I seal the joints correctly. Very well done.
I'm very happy to help, thank you for checking out the video, Bob.
I've been plumbing for 12 years, in Az, and you pretty much, covered it all. Great video 👍
Thank You Sandro, much appreciated! Bob
Are you anywhere near Kingman Arizona
@@paulcampbellsr.9818 he"s in NYC
@@deadmanswife3625 Paul is not in NYC don't know where you got that info. But either way I got it fixed
@@paulcampbellsr.9818 you were asking where bobsplumbing is?
Or where sandra is ?
Sorry I thought you were asking about the guy who is doing the videos
Thanks for the video. Well done. As a rookie I really appreciate the explanations why and when rather than just do it my way.
I try my best John, trying to perfect this video stuff,LOL! Thanks for checking out the video,Bob.
super helpful, Bob! Thanks.
Perfect explanation, so much to learn. Thanks!
Glad you enjoyed it!
I learned with lamp wick and pro dope in 1998. I had an old school plumbing instructor. Still my preferred method. I've used mega lock here and there. With the tape I learned to put the dope on first then the tape over it. Real Touff I mainly used for fire sprinkler systems. Blue block makes a mess, it's like paint and gets everywhere. I didn't do much gas piping, but I used it exclusively for oil, from the tank piping, oil filter, firomattic valves, up to the burner.
Thank you for sharing the knowledge.
My pleasure
Worked like a charm! Bought the better Teflon tape and used some Megalock from Home Depot...no more leaks! Thanks for a great video.
Fantastic!
Disagree with covering the first thread with Teflon tape. Keep the first thread clean for an easy start. I agree with you and also do not run the tape all the way up the thread, it's just a waste of tape as those threads will never enter the joint. The other reason for not cover the first thread is any tape hanging over the first thread and end of the pipe WILL break loose and enter the piping system. In some cases this might not be a problem but in others you never know where it might travel to. Solenoid valves in dishwashers or ice makers are two examples where you don't want fragments of tape to be.
Yep. Just dug up my gas line and every single joint had excess tape hanging inside the pipe.
It seems all sealants are good
You only tried 3, didn't actually pressure test any of them for a comparison test. You didn't try any UK available or oatey products. Please do a better video, also why didn't you bother putting the tape on properly.
When we get through this Virus situation, people are going to have a new appreciation for the Journeyman service men and women in this country! God bless all the guys who keep this country up and going , plumber, electrician, 𝐇𝐕𝐀𝐂, long haul trucker, under appreciated for decades! Need good healthcare that doesn’t cost a fortune or has such high deductible people live with their health problems for years, until they are dangerously sick!!!
Thank you! Stay Safe! Bob.
Excellent video, and one that even a woman can understand--now I know how to fix that leaky pipe in my well pit. Thank you!
Thank you! For checking it out. Regards, Bob
Did you fix it?
Thank you, Bob,
Spot-on terrific info and also a nice walk down memory lane. I'm 63 and my father (420 Steamfitters) started me off with Pro Dope and lamp wick, which is still nice for some old hot-water radiator repairs! Also, great review of different type products and specific applications which is more of what is important instead of debating (as I often see) whether Hercules, Rectorseal, Blue Monster, etc. is the best?! All of the aforementioned companies make terrific products, but knowing how to use those products is the key! Passing this on to friends....
Cheers
Thank you John! Regards, Bob
This video is so info packed.
Very nice video ,so many thing need to know. Thanks
Great vid. All the questions answered...covered everything. Thanks.
Glad it was helpful!
Thanks for this video!
I'm a plumber for the port of Oakland and I also use the tape and pipe dope combo and it never fails!!! Love the videos keep'em coming.👍👍👍
Emmanuel Lopez Thank you Emmanuel, much appreciated . Thanks for checking out the video. Regards, Bob.
FANTASTIC best of em I found
Great video...easy to understand..no loud music...thanks
Glad it helped!
I've used the BlueMonster Gas Teflon Tape or the Gas Rated Yellow Teflon Tape for years with gas fittings, especially on 2" or ST90's
Excellent - Great Teaching Skills
Thank you so much lots of good ideas appreciate everything you did
You are so welcome!
Great video. Thank you.
Thanks, Alexander, thanks for checking it out.
Thanks for sharing the benefit of your experience.
My pleasure!
Really great video and good explanations
Thank You Mohammed ! much appreciated, regards. Bob.
Good video. Thx. The devil is always in the details for us weekend warriors and you helped fill in a lot of them. I'm on the West Coast but if I were in NYC and got into trouble I would definitely call you to come out.
Thank you Joe! Regards, Bob.
Very helpful. Thanks!
Thanks for checking out the video Todd!
Tape and dope 👌 cool and informative video.
Thanks, I believe you solved my problem.
Thanks for this valuable content!
My pleasure! Bob
Yes Ricardo, and I speak from experience! Regards, Bob.
Bob great video and thank you. I was a pipefitter for the gas company here in St Louis 35 years. As you can imagine I've been through a variety of different pipe compounds (pipe dope) in my day . I ended up finding a correlation between the quality of pipe dope and my wife doing laundry. If my wife could get the pipe dope stains out of my work pants ,I found it was not a very good pipe dope but on the other hand if she could not get the stain out, I found those Brands & types to be the best. I found it surprising that the gas industry in New York does not allow yellow Teflon tape in certain applications. I find it absolutely necessary to use yellow Teflon tape and pipe dope once you get into the pipe sizes of 1 1/2" & larger with deep threads, such as Chicago service head adapters. PS Robert ,love your 1st name
I learned a ton watching this and love your attention to aesthetics and detail - thanks for a great post. On different note, your post made me think how fun it would be as a layperson to be at a convention and listen to the debates you guys must have about stuff like the myriad personal styles of joinery and applying teflon tape. Love it.
Thank you Zach, very much appreciated! Bob
Excellent video.
Thank you very much!
Excellent video. I love that fact that you take an extra few seconds to wipe your joints and make them look neat. Also although you didn't touch on it in the video I see sprinkler fitters using the paste and then a few layers of Teflon tape over it.
Robert Meier Thank you for checking out the video! Always wipe my joints down, the difference between a professional and a novice. Some use the tape first followed by the paste and visa versa. I guess it’s personal preference. As long as it doesn’t leak! Regards, Bob.
It’s actually better at least in my understanding that Teflon tape then sealant after, if you use the sealant then the tape the tape makes a balloon of sorts and it just gets pushed out of the fitting.
I just had to pull (lean over) a newly installed fiberglass shower stall. Teflon only had slow drips. Teflon and thread sealer did the trick. Something so damn simple biting me on the butt, but your video effort was well worth it. Thanks.
Happy to help, thanks for checking out the video~
Thanks! I think I now know why my 1.25 to 1. inch reducer is leaking/dripping on my pressure tank diy hook up. I over-torqued it and used only metal pipe dope. I will get a new reducer and use teflon with teflon sealant, and not over-torque.
Thanks, great video.
Thank You Mark! I try, thanks for checking out the video. Regards, Bob.
Great vid, well done!
The Girl In The Box Thank you for checking out the video! Regards, Bob.
Cool video. I used to use Real Tuff a lot many years ago and really liked it...I like it's silkyness and smooth texture. I got a can of Blue Monster today and it seems to be a lot like the Real Tuff. I think I'm really going to like it. Enjoying your vids. 27 year plumber here. I use tape and pipe dope on most things as well.
Tape and dope, you cannot go wrong.IMHO! Thanks for checking out the video. Bob
Great video. Thanks for posting1

Good information, enjoy your videos
Thanks for watching!
Very informative thank you sir
Thank you for watching! Regards, Bob.
Very informative.
Thank you.
Glad it was helpful! Thanks for checking it out! Bob.
Love the Megalock, discovered it by accident at Home Depot, just using it for water fittings around the house. Back in the late 60's/early 70's I worked for a gas utility, they exclusively used the old yellow Rectorseal. No teflon in it in those days. I always felt it just lubricated the joints, with high pressure mains and gas at 75 or so PSI, how could compound hold back the gas, it's really the compression of the pipe and fitting. We always called it pipe dope, never heard anyone call it compound.
Super helpful, thanks!
You're welcome!
Thanks bro. I liked and subscribed. Your video was very informative I am currently doing a lot of plumbing around the house and I am trying to soak up all the knowledge I can
Thanks for the sub! Glad I could help.
Over-tightening can produce water or gas title seal initially. Brass expands and contracts with temperature. This often creates hairline fractures that can be a bear to trouble shoot. The video is good advice.
Used Teflon tape first, then rectaseal, liked the smell of the pipe dope, but very rare if never leaked in my years of plumbing heating . The problem with Teflon and dope with Teflon, oil pump mfgs. Advise against Teflon, I personally saw a oil pump leak oil from a hanging furnace that the installer used plain Teflon tape. On water the combos can’t be beat. Very good video.
Pat Cupolo Thanks Pat, appreciate it!
thank you so much for the video.
Thank You for watching it! Regards, Bob.
Bleu block my favorite!
I like real tuff over Megalock but like you said it is difficult to clean for sure, almost like a white tar if that makes any sense. I’m probably using way to much. I think they lubricate more than they seal imo making it easier to tighten the fittings and also makes loosening in the future much much easier.
The teflon tape/sealant combination works well. I didn't know about the lamp wick and Blue-Block. Thanks for the video.
You're welcome Jason, thanks for watching!
Hey Bob. Great video. I know you don't need tape or dope on compression fittings (brass ferrules or rubber o-rings), but I like to put some tape on the threads because it seems to help control corrosion making it easier to take apart later if needed.
I'll use Teflon on pipe threads in combination with pipe joint compound. I tend not to use it on compression or flare fittings but will lubricate the threads with pipe joint compound to make up the nuts easily.
BobsPlumbingVideos OK. Thanks.
Very helpful. Thank you.
You're welcome!
I agree with megalock being much easier to clean up. That is why i mostly use it.
great video thank you!
Glad it helped! My pleasure.
Great video, gives a lot of important information for novices like me . Don’t edit down the length.
Thanks for the content; I genuinely appreciate it. Agree w/ prior comment about speed of delivery / length / time to get to the point, but not a big issue; some folks like longer stuff and some folks like high speed (Jimmy Diresta style 😂😂)
thanks Jimmy!
Thank you for blue block
First time viewer. Bob, you are one of the best! It's nice to see a pro do the teaching. I'll be using your tricks going forward :) Happy New Year bud!!!
Thank You Sir! Happy New Year to you and your family! Bob.
Thanks for the advice! I only put Teflon tape on a new kitchen sink shut off valve and it wouldn't stop leaking. I'm going to get some sealant tonight!
Good Luck!
BobsPlumbingVideos it worked like a charm
Did you use 4-5 wraps? But i know the old pastes and the new pastes work better. Just messy. I’ve seen pros use both wrap and paste together.
Very interesting
I use both at the same time primarily by the way (i work on sussman boilers in the 45-70 psi range)
Thanks for the video
Thank you for checking it out!
Love blue block for steam and gas, there is another product from Hercules that I use for gas is Grip (black) it works great as well.
Grip was the original leak stopper! Great product, messy also!
Yes, threads are imperfect, if you screw something (especially larger things) there is a bit of loose wiggle. Fine thread, naturally less. Good video, more to it than I thought.
Thanks a lot.
With threaded brass fittings, leave ~2.5 threads showing on the male connection as a general guide to avoid over-tightening the softer brass. Brass threads can warp, crush or distort if over-tightened.
If you don't make the brass scream, it's not tight enough.
Thank you good information GOD BLESS
So nice of you
Great vid...very informative...Thanks for sharing...
Thank's Chester! You're welcome.
thank you so much!!!
Blue block with teflon tape works in both new and old pipes because the new ones come with all kind of impurities also, you don't want to take any risk. Of course for the gas pipes only blue block on the male thread.
thank you!
You’re welcome!
Perfect and with enough options for me to figure something out in a hurry even if it's a Sunday and all the stores are closed, and we are in the middle of nowhere. Thank you! we're in a hundred year, old run-down summer house with plumbing, which is great, but of course there turned out to be two leaks when we turned on the mains, and I've never seen iron water pipes before
You're welcome and thanks for checking out the video! Regards, Bob.
My favorite stuff is blue block!! Love it!!! I use it on boiler piping.
Best insurance product ever I.M.H.O. Regards, Bob.
I agree! Trying to disassemble a connection, that blue block was applied, later is tough! You know that joint was sealed well!
PatrickNJ Yes blue block does set up a little bit in the threads. But it’s not as tight as other sealants so it allows you to get the fitting apart if you have big enough wrenches. Got my nice 24 inch harbor freight pipe wrenches and love them! Also like how you can use blue block as a gasket maker basically you brush it on one face and let it set up for 5 min then assemble.
thank you
Dope then tape. Fills in the threads better and comes out much cleaner. I'm a Fire Sprinkler Fitter and I usually do about 5 wraps. We use either Teflon dope or C5A copper anti cease along with Teflon tape
The age old trade argument. Lol.
