How to Assemble AN, Push Loc, PTFE, Crimp Style Fittings and Hose!

We get a ton of questions about the difference between PTFE , Standard Braided AN, Push Loc, and Crimp style Hose and Fittings. So we figured we would make a video detailing the difference in assembly, fitting style, line style and more.

Standard Braided AN Line / Hose: Must use Crimp or AN two piece wedge style hose ends. This uses a wedge to lock the hose together with the fitting. Must use rubber inside braided style AN line. Available 4AN 6AN 8AN 10AN 12AN 16AN 20AN and larger in some cases.

PTFE style line 6:30: Must use PTFE style fittings with inner Olive / Ferrule. PTFE line should be conductive style to avoid arcing if used with fuel. PTFE line is much smaller OD than standard braided AN line and can not be used interchangably.

Pushloc 3:10 : Interference barb press on style hose. Not allowed in some classes. Check local rules for usage and legality.

The fact you guys take the time to call the customer when an order doesn't seem right to make sure they ordered the right stuff is going way beyond what any other company does, and the fact you guys did that on an order recently for me blew me away. Definitely made me a customer for life.

That ptfe fitting jamming the olive in jives me the shivvers - i can just feel the metal braiding going up my fingernail watching this!

[matt]

Thanks for including pushlock for us poor people!

[kennieholt]

I am a new customer due to the way they treat their customers and the informative videos that make it feel hands on and less confusing. I will be using these guys for quite a bit of my 3rd gen Camaro build. Keep up the genuine honest videos guys i appreciate them.

[VanaConn]

Thanks for the info as I dive down the AN rabbit hole for the first time !

[tyrvidar]

This is probably the best AN related fitting how to top to bottom I've seen on the net yet. Great stuff man, my first time utilizing PTFE I appreciate the break down !

[Lordspaghett]

Good to know I did the PTFE fittings halfway right on my build, I whacked it on the ground until that metal ring was flush against the fuel line, no leaks!

[gregory]

I was unaware that ptfe hose was different than regular an hose so had to order different fittings for the an hose I ordered, thanks for info.

Nice video, thanks for taking the time doing this. I have had great luck with Aeroquip AN hose and fittings. Pretty easy to assemble and bulletproof. Used a hacksaw to cut it after wrapping with duck tape. I have had this hose on my '94 Z28 for about 20 yrs with no problems whatsoever. I noticed the prices on this stuff have gone thru the roof.

One of the best out there to explain easy and fast without any annoying talk about something elso or some sponsor shit.
Straight to the point. Good!

One tip is to use a bit of electrical tejp to just se if the hose is mowing away from the fitting. just take a bit and place right behind the fitting. Then you can see if the hose is all the way in or you should redo the work.


Angle grinder and so is a bad idé. They just send small stuff inside the hose and that is going inside yours injectors. The fuel filter will not take all of that.

Great video for the uniformed as well as a great refresher for the occasional user.
Thank you for sharing this information.

just learned the difference before i spend lots on the wrong parts.thanx

Those cutters are awesome! When you don't pay your bill at the shop, fingers comes off so easy. 🤘

learned a trick from a guy who ran a Pontiac nostalgic top fuel dragster on metal braided AN hose, put just a little bit of electrical tape on the end (one, maybe two layers). Keeps the braid from fraying out and going crazy when you are assembling the hose, and doesn't interfere with it staying sealed.

Love watching 4 wide racing, must be intense and full of adrenalin. Love your work Clay. Looking forward to race day

[gafrers]

Great video and very well explained.
11:25 Carbon fiber is electrically conductive. I haven't seen any indication of the Nomar wrenches being electrically insulated

[Chubbza]

Legitimately here because I was about to call my supplier and ask wtf fittings he sent me with my hose. Thanks man! It sounds like you've picked up quite a few questions from people like me.

Depending on who’s brand push lock hose you’re interested in purchasing, you should check to see if it’s compatible with gasoline. Some push lock hose is not compatible with modern gasoline and was never intended to be used for that.
I pressure test hoses after assembly and when I received my first high pressure pump and made my first test fixture the first thing I tested was push lock hose. The working pressure of the test piece was 250 psi, the test pressure should have been 500 psi and the burst pressure should have been 1000 psi. This piece of push lock hose burst at 1300 psi. It is not intended for high temperature, I never recommend you use it for a coolant hose. There are enough errors in this presentation from this man to lead you down the wrong path on many items. What I recommend is that you read a lot and understand what you’re doing or get someone at a hose company that knows what to do. The biggest problem we have with racers is that they think they know what they’re doing and they end up bringing half the stuff back because they ordered it wrong. If you are cutting PTFE hose, use filament tape at the area where you’re going to cut and cut through the filament tape. Leave the tape on the cut until you’re ready to assemble the fitting, one end of the braids will be tight against the PTFE and the other end it will flare out away from it. That is why you only saw him do one end of the hose. I don’t feel like going on for an hour or so I’m quitting now. He means well. Follow any guidelines you can find from Aeroquip. Basically everything is on YouTube.

If you don't do it already you should sell a kit of hoses with crimped ends on it already to go on your website that way you have another product but it will save a bunch of driveway builders a bunch of time and headache of having to put certain ends on certain hoses and killing their hands and save them from hunting down tools you don't have and so on plus crimped end hoses are pretty universal and like you said it's one of the best ways to make an end for a hose if you have the very expensive crimper

I've seen a lot of how to videos for auto RnR. Great job, very direct and clear. Thank you.
