DOT air line fittings?

[Mos68x]

I'm considering changing some fittings while I replace air lines. Has anyone had any experience with these?

They work good.Just make sure any fittings u buy are DOT approved.

Like Mr. Appel said. The most important question is, do YOU trust them with your life and the lives of any passengers ?

They are DOT, I was asking more about personal experience. Such as...are they really "tool-less", and can you remove the the hose from the fitting without damaging it?

I switch mine to hydraulic lines as they break or I have issues with fittings. Easier to find places to make hoses as well as you can interchange a lot of them as you can the plastic lines if a component fails but the plastic does like to bend certain way sometimes.

I have used the brass Parker push lock fittings with no problem. They are great where space is tight for a wrench to tighten the line compression nut. And yes the line can be removed easily without tools. The other advantage is the brake line doesn't twist as you tighten the nut. The only negative is they usually cost a bit more than the regular fittings.

The tool I have seen for taking these fittings a part will let you reach up into places where you can only one hand and it grips the line and pushes the lock ring then pulls the line out. after that you push in the new line and pull back and your done .

We use alot of the all brass Parker fittings like that and have had no problems with them. There is a tool to help push the lock in, and sometimes washing it out with brake clean prior helps to.

Yea it isn't worth it. No where near worth it.

Yes, I have them all over my truck. I have only used the all brass types. All my brake system lines are DOT nylon and these fittings are much easier to work with. You will thank yourself for the transition.

I would say say buy what you need with maybe a few extras. I get them from McMaster-Carr, Discount Hydraulic Hose or eBay.

I use McMaster A LOT lol that'll be just another thing I use them for. I might even use them for new o-rings for the rims since I have at least three I have to disassemble and clean out RTV from someone else.
