Push-in air fittings

Sapper · Mar 3, 2004

I was at a truck supply (Semi, IE peterbuilt) store and saw these push in air line fittings that are DOT approved. I think they would be the bomb for plumbing in an OBA setup as well as lockers. The unions are simple to use and reusable. I think they would be a great addition to any vehicle with OBA or air lockers.

That is the best link I could find to them but I would like to find a better one or even an online source.

I have used those and they work great. I have them on my OBA for the front locker. I used some super tiny, easily routed and easily replaced tubing on my front locker, and it's tiny enough to keep a little spool of it in the Jeep.

As far as mating it to the bulkhead fitting on the ARB, that was a tricky one. I broke off my jingus metric to NPT fitting once, so I went back to blue line, but when I go back to the tiny line I'll once again use the push in fittings.

Got my fittings and tubing from http://www.fittingsandadapters.com

Great service and good prices.

McMaster has over 10 pages of these fittings. Search for "Instant tube fitting". Many, many different materials to choose from, several types of plastic/nylon, PVC, ABS, brass, nickel plated brass, stainless steel, etc. Metric sizes too for ARB lines and very good prices.

I've used different sizes for all of my OBA, water injection, boost gauge and a 10' vacuum line for a MegaSquirt's MAP sensor.

BTW, they have the nylon tube as well. Get the Nylon 11 stuff, it's a bit more flexible than the Nylon 6 stuff and will bend around corners better.

They are air brake fittings.

EBSTEVE · Mar 3, 2004

Low rider air bag suspension guys use them all the time so searching for that might get you some online sales places and some interesting reading on how to chrome stuff as well :flipoff2:.

I buy the fittings locally at a hose and fitting place and they add up quick.

No joke? And you know what, D60s are built for 1-ton trucks...

We used to use these in technology class, but only for low pressure stuff, I wonder how much pressure they would hold up to and if they mind dirt and crap...

Mine work fine with 100 PSI.

Sapper · Mar 3, 2004

Well apparently all the new Semi's use them for all of thier fittings. I know that they run at least 120 psi in those trucks and they are DOT approved for that use as well. They are a bit more than your average fitting but areas where you may snag, break or melt a line they would be ideal because all you need is either a union in your tool box or spare line and replace as needed.

I asked about the mud or salt on them as well and if you stay with the brass unit they said there was no issues. The salt here is UNBELIEVEABLE on the roads and these trucks see many more miles than my rig will see and that is why I will be using these for many places.

I just hate compression fittings.....

EBSTEVE · Mar 3, 2004

I had 155 PSI with fittings that were like that but plastic. I don't recall what they are rated for but it was well more than I ever thought I would need.
I know the 3/8 line (DOT 11 air brake) that Parker sells is rated for fuel line so gas wont eat the line and I am sure the fittings are the same.

I checked out the mastercarr site and saw alot of these?

So these are basically tool-less fittings? You just push the tube into the fitting and their is some sort of retaining mechanism that keeps it together?

That is pretty cool... definetly keeping a couple in your tool box would help make good trail spairs.

Your statement is off topic.

I run the air brake fittings and 3/8" tube at 120psi daily, no issues.

Tippy · Mar 4, 2004

I use a plastic version for my OBA @ 125 psi. We use them at work for some air valves and for our fertilizer spreaders, so they were handy. I haven't had any problems. They make them in 1/4" and 3/8". The ones that I used are not DOT leagal, but any decent parts house should carry the ones that are. I know our Carquest carries them.
