- How to Assemble & Test PTFE AN Fittings ( Teflon AN Hose Fittings ) Today we are going to look at Army-Navy Fittings or AN fittings, how to assemble them as well as how to pressure test a fitting to make sure that they don't leak. The AN fittings are available in virtually an endless selection of types, angles, and styles. In this video we are going to be looking at specifically PTFE or Teflon AN fittings. Teflon or PTFE has multiple advantages for tubing. First, PTFE ( Teflon ) is unaffected by any type of automotive fluid, even alcohol or methanol. It has no affect on the tubing making it the preferred choice for fuel line. PTFE line will also withstand higher pressure and temperatures than standard AN swivel type line. Most PTFE line will withstand over 1000 psi and 400F making it useful in even power steering or air conditioning systems.

Doesn’t matter how much I think I know from 40 years of mechanical experience I always learn something watching these videos! Another well put together presentation!
This is the best AN hose/fitting video ever.
I was going to use some Viton lined hose for my fuel system but will be getting PTFE instead i think. The use of ferrules looks tedious but worth it.
Never seen those test fittings, pretty sweet
this was a fantastic video
Awesome video! Excellent method to checking the seal.
Excellent demonstration. Thank you
Excellent tutorial man. Definitely gonna do this for my hose systems on the 73’ Crew project.
Keep up the awesome work.
great video. Hardened cable cutters work better. No dust or wire splinters to deal with. After cutting, simply trim the crimped/pinched end of the PTFE off with a razor blade, nice and flat. Also, use a pocket screw driver to gently separate the steel braid from the PTFE, then push the ferrule into the line.
Thanks for the explanation👍 on those PTFE fittings, great video.
Good job, well explained, easy to follow. Thank you, you are great.
Awesome video! Thanks!
Great video and very informative. Thank you!
Hello again Repair Geek
Thank you for another Great Video 👍 As a Aircraft Mechanic I have to thank you for the presentation. You were dead on!!!! Although, on aircraft the hoses are already built and pressure tested. One thing I would suggest is instead of using a vice. Try a Ford Wrench. It's a smooth jaw pipe wrench. The story told to me was Henry Ford and the Model T. The Ford wrench came with the car. Using the Ford will not mar AN fittings. Again thank you 😊
A damn good no nonsense video👍
Thanks you for the information 🙏🏼🔰
Very helpfull and perfect with details👍🏻
Great video
Outstanding video! One thing though - back in the day we put tape at the end of the fitting and if a gap appeared it meant the hose moved - is this not accurate?
New subscriber 🔥🔥🔥🔥🔥
Great video..Thanks...THe only thing I ask...Is if you don't cut the hose straight then hoe can you correct it (making it perfectly straight)?
What is your opinion of the evil energy hose and fittings? I was planning on using Fragola, but if I can get acceptable results with evil energy I wouldn't mind saving a few bucks.
What brand is this? Ive never seen the nut slide over the braiding that easy!
Would using a band saw work fine cutting this hose, & assuming if yes, would give you a clean cut?
Thx for the vid, love learning something new, even after many many years…..can always learn.
It probably would, you'd still have debris inside the hose after cutting though.
A hacksaw with a FINE blade would probably work... like 32 tpi or finer.
Got a question.... Would this be a good system to connect the output from an air compressor pump to the input to an air cooler. I want to add an air cooler to my compressor (to dump dry air into my tank) and have seen where hard connections (copper tubing) can fatigue at the cooler from the pump vibration NOT being isolated.
I used copper on my compressor air cooler 5 years ago and haven't had any issues. I've put about 100 hours on the compressor since then. Yes these lines should work for that application as well.
Hiya Is this an ebay spec ptfe hose?
I LOVE YOU
Can the ptfe stainless line with aluminum fittings work for custom clutch lines?
Possibly, I'm not certain. It would depend on the amount of heat in the area and the amount of pressure required in the line to actuate the throwout bearing.
When pressure test swivel hoses, I can see air bubbles from the little hole on the nut fitting. Is that normal?
Yo I have the same issues right now
I have the exact same issue, leak at the little hole on the nut. Any thoughts on how to address this? I also posted the same question to Jegs, will let you know if I hear back from them.
@@RoyW. I meant no more bubbles after I put wd40 on the hose ends before assembling.
@@RoyW.I had the same issue, was caused by a crack in the female end’s internal mating surface.
is using this on brakes the best choice?
Don't use this for brakes.
Does PTFE work with diesel fuel?
Yes sir.
Is this stuff street legal or is it just for race cars
With my 45 years of experience assembling race, hose and industrial hose that PFT hose was assembled incorrectly. I would not be surprised if that end leaked or came off the end of the hose. during a working pressure test !
If you know how to do it why are you here?
Great resume, rather than blindly saying it would leak. How about describing why and educating the right way (your way) to do it?
I was fairly impressed until you recommended cutting the hose with an abrasive wheel. That is amateur on steroids. If you can afford PTFE hose, you can afford a proper hose cutting tool. They really aren’t that expensive and they a faster, neater and much cleaner than an abrasive wheel. Sheesh.
Haven't found a set of hose cutters that don't bend or crease the inner plastic hose. A cut off wheel is actually better.
