Excellent PSA, thanks for the detailed breakdown. In the early days of this, I was having a hard time finding raintight and I could find concretetight. I thought well, poured concrete is wet, so it has to be good for raintight too. WRONG! At least raintight is fairly easily available now.
Consider doing a session on drains and breathers, big issue as you are aware for enclosures, conduit systems .....I'm in the explosion proof business with Eaton, many issues on sweating and condensation ! The tighter the system, the more moisture and condensation is an issue ! Great site, I learn something every episode ! Bill in Canada
The only time I used EMT with raintight couplings in a wet location was on a greenhouse. Have seen a couple of times used outside on small commercial jobs, but mostly PVC and RMC is used.
Hey brotha question that an answer from you would really help. Do they have a 2 inch rain tight EMT connector to 2 inch rigid connector. More specifically a 2 inch rain tight connector to 2 inch male rigid connector
@Electrician U . I went ABC trade school for my electrician NCCER. I recently finished it and need to take the NCCER test for. Can you explain what is it useful for? I try to ask my teacher but he did not explain it properly.
Is this what I should use to couple buried emt? I have some I’d rather use than pvc and I read that emt is approved to bury as of last year. I just need to join two lengths underground
On the side jobs I totally don't do, I always use raintight. At the company where I work they don't wanna pay and they're old timers so most of the time the foreman just buy compression 🤷♂️
Amazing to me is that I started running EMT back in the 1960's and used compression fittings outdoors & wet locations but think the first time that I came across so called raintite fitting was at most 20 years ago. I stay away from all garbage die cast fittings especially POS made in India.
I’ve used compression fittings and applied silicone sealant to ends. Silicone will last for decades as opposed to the cheap plastic and rubber used for gaskets. Those things UV rot after a few years.
Indoors, I just think those compression fittings look better than the set-screw type. And it's a lot harder to over-tighten the compression fittings too, so they're harder to mess up installing as well. And the rain-tight fittings looking nearly identical to the compression fittings once installed can make some of the laypeople that don't know any better not think to ask a question about why you used a different kind of fitting here vs there, which is nice. Don't get me wrong, I'm happy to explain, but time spent explaining is time spent not doing work, unless you're a teacher.
I always wondered about that. It never made sense to me (just a DIYer BTW), that ordinary compression fittings would be considered as water tight/liquid tight/rain tight/wet location or whatever tight - and never used them that way. Now, I wonder how (of if) UL actually approved them for that environment or application. Are packages still marked that way?
Compression Coupling connectors ONLY used for Inside the house never outside the house? and Compression coupling connectors are ONLY used in Non-wet environments?
You'll very seldom see a compression OR a rain-tight fitting inside a house in the first place, because that's residential work and most of that stuff is just using NMC aka Romex (unless you live in the Bronx or some other places, in which case you'll be seeing armored cable instead, which has its own fittings). EMT and these fittings are more often seen in commercial/industrial settings. EDIT: But to answer your question, if you're using EMT in a location that the code considers a "wet location", then you must use the rain-tight fittings, not the compression fittings. In areas that are not considered wet locations, you can use rain tight fittings, standard compression fittings, or set-screw fittings, all 3 would be code compliant (the code doesn't ever say you can't use something that's overkill for the task, that job is done by your wallet).
@@44R0Ndin when would electrician use compression fits and connectors and couplers instead of using the rain type connectors and couplers I don't know when the technician electronic technician will determine if they should use compression couplers and compression connectors or rain tight like how would it how would they decide and make a decision on which ones to use anything to determine any tips to know if it's like a cut and dry situation on knowing when to pick between compression and rain tight
@@waynegram8907 I can make this pretty simple for you. If you have a roof over you, chances are you can use regular old compression fittings unless you're like in a car wash or something. If you're outside, you gotta use the rain-tight ones, because of the... well, rain.
@@44R0Ndin I wonder if you can use EMT on wet or damp locations. My understanding is that NEC only allows it to be use indoors/dry location. Thanks for your comments
@@lrsotog "can't use EMT in wet or damp locations" Can you cite what part of the NEC states that you can't use it in wet or damp locations? I doubt you can, and I'm also not sure if you actually believe that or if you're trolling. C'mon, I'm sure you've got enough brain power to figure out something this simple. Here's a question for you: What do you think the rules are about EMT usage in wet locations, if they make so-called "rain tight" fittings for EMT? If I've misjudged you and you can't put the puzzle together for yourself, I'll do it for you right now. Yes you can use EMT in wet/damp locations, provided you use the correct junction boxes and EMT connection fittings. Rain-tight compression fittings are one type of fitting approved for use alongside regular EMT in wet/damp locations, provided you also use junction boxes and other things that are ALSO approved for use in wet/damp locations. Yes, I was being intentionally condescending and talking down to you in that last paragraph, not because I think I know it all, but because it seems to me like you're intentionally playing dumb and I hate when people act like that. I've found playing dumb like that to be almost always counterproductive and obstructionist. But furthermore, if you actually watched the video you'd already know the answer to this question. I'm guilty of sometimes posting my comments before the video is over too, but I'm usually able to put together facts that were given to me in the video title and/or thumbnail in order to figure out what would be an entirely wrong thing to say. Keep in mind, we're not talking about running wires underwater or in a tunnel below a river here. Just "wet or damp locations" aka where things get rained on or otherwise wet. Basically car washes and boiler rooms and outdoors, that kind of place. As long as you use the right stuff along with it, EMT is perfectly suitable in most places. Where EMT is not suitable, MIC is probably what you need. MIC stands for mineral insulated cable, and it is used in nuclear reactors and other extremely demanding locations where there is either a demand for the ultimate in reliability or there is a high likelihood of physical damage, as MIC is generally more robust than most other forms of electrical wiring system. Additionally, if the outer sheath of the MIC assembly is not breached, it is next to impossible for a wiring fault to escape the sheath, which makes it useful in mines as well where sparks are to be avoided at all costs.
Those rubber gaskets and i-rings and yellow washers on the terminal end fittings are cute but pretty useless after a couple years. They dry rot, UV damage and then crack and fall off and now you have a 3/32" gap. Throw out the washers and Pipe dope or thin Teflon tape, but you still want to maintain the bind so not too much sealant. blessings
The regular non-rain-tight compression fittings are less expensive than the rain-tight ones, and IMO they look better than set-screw fittings in locations where they are permitted to be used.
Okay raintights are intended for use outdoors. So in what application would you use a compression tight? Indoors? They already have regular couplings for indoor use. If you ask me they should stop manufacturing compression fittings. Sounds like a micky mouse job.

And some of the wife's hair ties to make it looks like it has the gasket.

Lol same
thanks dustin on the tips ill start using the rain tight for sure now i didn't realize the change

When screwing on ur rain tight connector to a ridged coupling do u take off the lock ring for the connector and if no if that illegal

Still confused about raintight and wet location difference
Bro how do I get my boss to watch this
Why not just discontinue non-rain tight compression fittings
Because this way they can charge extra for the extra feature.
5-pack 3/4 compression: $5
5-pack 3/4 rain tight compression: $8
The regular non-rain-tight compression fittings are less expensive than the rain-tight ones, and IMO they look better than set-screw fittings in locations where they are permitted to be used.
Cost. And that the overwhelming majority of compression fittings are used indoors.
Nothing , used outside , is gonna keep 100 % water out … so there’s that …
Okay raintights are intended for use outdoors. So in what application would you use a compression tight? Indoors? They already have regular couplings for indoor use. If you ask me they should stop manufacturing compression fittings. Sounds like a micky mouse job.
Concrete tight isn't the same.
