air line parts

[b52rule]

Low and behold all the air lines from the valve assembly leak at the gray
plastic fitting coming out of the air valve solenoids.

I pushed them in but they still leak.

Suggestions?

Len,

The OE plastic fittings were real good for about the first 10 years, after that they are a problem.

OK, its a 78, but is it EL1 or EL2?
That does not make any huge difference, but the adapters for most of the air lines in either of these systems is a:
1/4NPT male to 1/4 Compression DOT fitting.
Just go get as many as you need. Do not use teflon tape unless you are very good at using it.

Screw it in and then recut the plastic tube to straight and square. Shove it in and crank the nut down 1-1/4 (7-1/2 flats).

Thanks! I found some new plastic fittings on the spares box from the PO.
It still leaked. I'll order parts tomorrow.

Any "good" auto parts store has them in stock. The brand name is Parker. Not available from AZ or Advanced. NAPA has them at double the street
price. I went through and replaced all of mine about 15 years ago. Most were straight ones but I did use a few 90 degree ones also. At the time
they were #1.50 each or $3.00 from NAPA

If you want some added security. I use Loctite 545 to seal up my air fittings. Safer than Teflon tape and won’t harm anything.

Never use teflon tape on a 'compression' fitting. It serves no purpose.
