1/4" air line
Had one that developed a leak today. Started the rig this morning and after switching off, heard some air hissing from near the air dryer. A quick look and there a small hole. I couldn't feel or see any reason to have caused a hole there.
It should be an easy fix so I got a coupler and cut out the bad part.
I'll be replace the entire line later on. Those PTC fittings are kind of cool.

I had one fixed under warranty, they told me it is common that when they are doing welding while building the house hot pieces of weld melt the line.

I agree, looks like welding splatter got on it. I carry couplers in 1/4, 3/8 and 1/2" just in case.

I'm going to end up carrying more replacement parts than I can believe.
Live and learn.

Could you show a picture of what you mean when you say "coupler" on the air lines? Especially in regards to repairing an air line. I tend to think of air lines made of "black pipe", and the picture shown looks like tubing of some kind. And I do want to carry the right spares!

The chassis is plumbed with DOT approved air lines which range from 1/4” to 1/2” and use a plastic or brass push to connect fitting. In this pic you can see the black plastic push to connect coupler and a brass push to connect Tee.

Our S2RV rigs have several colors for the air lines. Originally, I had thought it had to do with size of the lines but it didn't.
I ordered several sizes of straight unions for spare parts just in case.

The colors determine what circuits they are to make them easier to identify and trace.

I ordered excessively, figuring i could help others in my travels. 40 pieces of 1/4, 20 of the 3/8, and 20 of the 1/2 was still under $40.

I haven't traced them yet but that's really cool. So many things to do in the last seven months. I'll get there.
Tomorrow starts my big trial for my solar project and I'm really looking forward to that!

I know that these may only be used in an emergency but any fittings must be DOT approved.
Here is a sample schematic of one of the air systems. Note the table on the right shows the colors and the diamonds along the line drawing has the color code in them.

That's helpful. I can return them or even cancel shipping. I guess I don't know exactly what to get then, but will try to research it.

Just search "DOT approved air brake fittings" Personally I get either Eaton or Parker fittings and usually just pick them up at a Napa store.

Can the air lines be removed from the couplings once inserted? Just added airbags to my TV and plan on keeping a few spares.

Yes, if you push the small colored collar towards the fitting, you can pull the line back out.
