Nathan demonstrates the complete air conditioning hose assembly process step by step. For additional information visit www.royalbrassandhose.com/air_...
1st attempt at this technique: the brazing only bonded with the male-side tube. Probably not enough heat in female-side. 2nd attempt: I gave it more heat... too much. I melted the connection point and it slumped over in my vice. 3rd attempt (after cutting the tube back further and getting a new female-side): Worked like a charm! You make it look easy :)
Your a good man for sharing your knowledge, this is very helpfull for me on semi trucks because replacement a/c lines run in the hundreds of dollars. God Bless You.
This is great. I am about to have new hoses fitted to my truck. The repair place mentioned welding the hoses and I was worried it was a bit dodgy but now I see what they meant. Thanks for the video.
Hi, Nice video. I owned an automotive air conditioning and radiator shop for 30 years. I opened it in 1973 and it is still open today by a former employee. I have few comments: (1.) I was taught to clean aluminum with a clean stainless steel wire brush . (2.) I would not have dipped an A/C fitting in water. (3.) It was always a complaint of mine that they didn't make A/C hoses with reusable fittings in the first place. (4.) The R-12 hose barb fittings could be reused. They wrer held on to the hose by the center of the hose. We double clamped them or crimped with A/C hose ferrules. (5.) Barrier hose does not use hose barb fittings to hold the fitting to hose, but uses a bubble crimped ferule. (6.) I experimented with adding A/C hose crimp ferrules to factory hoses and then bubble crimp them. One method I used elongated the hole in the crimp ferrules so it could hook onto the factory hose fitting. I have noticed that some company uses a cage assembly and then special clamps.
Hi saw your comment and wondered if you had any advice for an old fart trying to block off my AC at the rear of my transit van . Seeing the aluminium welding technique I’m wondering if I can flatten the pipe ends leaving a small gap and aluminium weld the end . I live in the uk and having difficulty getting compression fittings to do the job . Thank you
Well, I was curious about technique. But equipment will be too expensive for a one or two time use. Think I'll just have it repaired. However with this knowledge I could do it if so inclined and if it was cost efficient. Thx for posting
My question is what kinda “solder” are u using? Led 60/40 or an aluminum braise rod with flux paste? Or silver solder? Flux core, cant be.. but if they hold up to that high pressure and the hot cold differential, im game..
What if I can't braze to save my life? Can you do this for me? If so, how much would it cost? Keep in mind, I'm not wanting to do this to save money. I'm wanting to do this because I have a classic Toyota where the hoses are no longer available, from the factory or aftermarket at any price.
The part where the bolt goes in to tighten the hose assembly to the compressor, is it able to rotate around the pipe? I have another compressor whose bolt hole is on the opposite side as compated to the old compressor but without removing the hose I cannot tell.
What I don't understand is why you can't just re-use the existing fittings instead of hacking them off. That way you would just have to replace the ferrules and the hose, and you wouldn't have to solder at all.
You mentioned flux in the cleaning process, but not during the brazing process. Did the fittings or the solder rod have a flux in it or do I need to use some kind of flux compound?

Amazing and perfectly done
So thanks to you. I have a problem with my 1997 Infiniti Q45, ac pipes are hard to find. Now I will make some by myself. Thanks a lot.
This gave me a good laugh this morning. Good Luck.
That's my brother! Great job! Andy liked this video😄
Excellent video. Thank you so much. :-)
fantastic video.thank you!!
Good job, what kind of welding line are you using for?
Excellent thank you that help us a lot.
Do you use a swage tool in case you have different sizes ? Thx for the video.
pre-fluxed alluminum brazing rods.
Ideally, for aluminum soldering you want the flame temp to be 600 degrees F to 800 degrees F
Thanks a lot for this video Where i find this tool to fix any leak?
nice work sir
Great video very helpful
Thank you so much

what brazing rods did you use? (flux)
My question is what kinda “solder” are u using? Led 60/40 or an aluminum braise rod with flux paste? Or silver solder? Flux core, cant be.. but if they hold up to that high pressure and the hot cold differential, im game..
Yes what type of rod is it. Went to suppliers and they didn't know
I have the same question
@@markivanenriquez5460 Pre fluxed aluminum rod 18" long.............. can be found on many websites , EBay, Amazon, etc.
@@sullyrower100 I buy mine from parts master. It's 5/64's aluminum rod that contains a flux inside it
AL822 brazing rod is what I use.
I need the fitting that go onto a citroen air conditioning condenser
hello, what kind of solder do you use to solder the pipes and at what temperature do you solder?
AN soft jaws might help on holding fittings too
What do you call this fittings becaus so I could know what to look for
Does napa carry this sleeves?
Where would one get the metric pad fitting? How would you clock it to the proper screw to pipe orientation? I am not an A/C man.
We don't stock the metric pad. The orientation is covered in the video in the part about marking on the hose and fitting. Good Luck.
What kind of Rod did you use
What if I can't braze to save my life? Can you do this for me? If so, how much would it cost? Keep in mind, I'm not wanting to do this to save money. I'm wanting to do this because I have a classic Toyota where the hoses are no longer available, from the factory or aftermarket at any price.
Just give Nathan a call in our Knoxville, TN office 865-558-0224 and he will see if it's something we can do for you.
Thank you.
The part where the bolt goes in to tighten the hose assembly to the compressor, is it able to rotate around the pipe? I have another compressor whose bolt hole is on the opposite side as compated to the old compressor but without removing the hose I cannot tell.
I've have asked our AC expert and without seeing a picture with your question it's hard to give advice. Can you supply a picture?
@@robinsmithson4565 How to send the picture to you?
Where to get those kind of fittings?
a better alternative is klimklamp kit !!! www.ekolinkstore.com
Junkyard i would try...
I need one did for a Oldsmobile
Where can I get those weld on fittings
Company called "Ranshu".
Hi is it possible to do this in the car for an oil cooler?
If not is there another method to get aluminum onto rubber while aluminum is in the car?
Not sure, you would have to contact a mechanic on that one. Good Luck.
I have repaired many oil cooler lines this way. The parts and the hose are more than adequate for oil cooler lines
Whats the name of this kind of clamps?
What is the brazing rod made from ?? What is the flux your using ???
the brazing rod is aluminum prefluxed
What's the crapper called I want to buy it
why not cut the crimp lug n reuse the fitting with new crimps
Jose Martinez the new crimp as you call it won’t fit over the fitting.
@@jorgenunez1825 yes it will. th-cam.com/video/osZ8QL5f5dc/w-d-xo.html
@@Dwbolan77 working in flipflops.. the last thing he needs is safety glasses.
Brazing with what? Solder?
I tried this with no luck .. what rods are you using?

so sorry, but currently we only ship to the continent of The United Sates
What I don't understand is why you can't just re-use the existing fittings instead of hacking them off. That way you would just have to replace the ferrules and the hose, and you wouldn't have to solder at all.
That's a really good question. Maybe he is selling the fittings?
The fitting is crimped on to the hose, and is therefore single use. It can't be undone.
Where can I send my hose to be fixed? I have no need to buy a crimping tool I'll use once.

The web page doesn’t show those kits
we sell a kit for repair shops to repair these assemblies.

Thank you.
Wow ITS very much
La crimpadora que modelo es?
It is a hand held Hydra-Krimp AC crimping tool.
Safety glasses to cut aluminium with hack saw 😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂
Don't use brake cleaner the ingredients can turn into a poison vapor with high heat and you can succumb very rapidly!
thank you
You mentioned flux in the cleaning process, but not during the brazing process. Did the fittings or the solder rod have a flux in it or do I need to use some kind of flux compound?
yes, we use a .063 aluminum brazing rod
refridgerant fittings
You forgot de long side without nut..............the nut is missing
Another channel said don't use flux??
I'm confused 😕
forgot the nut

This is excessive..
