Air line size

[USN_Green_Addict]

Does anyone know where I can find these lines and fittings? Or is there a way I can buy them pre-bent?

I forgot to put the rest of the post.
Went to move me truck today. I had 90 PSI of air, brakes were adjusted good. I only drove about 100 feet. Without any warning while sitting at a stop I presses in on the brakes saw steam come from the engine compartment and the brake pedal wasn't as firm as it was when I first started it up. Now when releasing the brake pedal I hear what sounds like air. I looked in the engine compartment and the air line that runs parallel with the air govenor line looks like it may have a kink. My airpack is freshly rebuilt. Any ideas of why this may be hapening or is it the possible kink?

Doubt you will find them pre-bent , they are just copper tubing with ferals , the nut is re-usable but you will need new ferals . You could replace the with plastic tubing rated for air brakes , if you have a Parker dealer near you they should have everything or your local heavy truck parts supplier .

Are you losing brake fluid ?

 

[USN_Green_Addict]

Yes brake fluid is coming out the vent. Pic is of what happens when the brake is released and at 90 psi. Hard to tell without the video playing you can see it coming out of the vent. And yes air tanks were purged prior.

Your air-pack has failed.

You might as well go ahead and replace the compressor to regulator line, and the 2 under the dash while you are there... I had air leaks at the pressure gauge AND the front axle switch. Cost less than $25 to fix them all... Air leaks SUCK. Especially on a system that uses air pressure for ALOT of things. Plus, field repair capability majorly increases with the new Nylon based lines, as opposed to the old copper stuff.

Is it typically just the plunger? Or could it be another part? I just bought one from seco parts in Georgia. Supposedly a new assembly.
