Constantly chasing Air Leaks
I've been on air ride for a few years now and have constantly chasing air leaks. This past winter, I pulled everything apart and checked all fittings in the bag, switches, and tank and can't find any leaks.
I always switched out some of the PTC fitting and put in brass T's to avoid them from leaking and still have a leak on opposites sides. It'll hold solid almost 24hrs then it will slowly bleed off. Any tips or suggestions for stopping the leaks? |

Re: Constantly chasing Air Leaks
1st, figure out what is leaking..soapy water will help...
other than that, age of your tubing may be a factor...id replace all the tubing and see what happens...what type of fittings do you have...pushloks?

Re: Constantly chasing Air Leaks
Use solid copper or cunifer tubes and fittings.

Just didn't know if some other method was out there. I've made sure all lines are cut perfectly straight, all fittings are teflon and locktite. All that fun stuff. Just seems never ending. |

Re: Constantly chasing Air Leaks
This is what we use in the hvac field, and works alot better the soapy water since it sticks. This hopefully allow small bubbles to form.
https://www.amazon.com/Nu-Calgon-418.../dp/B00E0Q03KM There are other brands, but this is usually whatbi use due to availability. I am sure any name brand is fine. |

Re: Constantly chasing Air Leaks
Where are you sourcing your airline & fittings from?

Re: Constantly chasing Air Leaks
A few different places. My original kit came with brass fittings, but I found them to be leaking inside the push connect so I ordered some from McMaster that I read about in another forum.
Do you have any suggestions? https://www.mcmaster.com/push-to-con...hes/shape~wye/ |

Re: Constantly chasing Air Leaks
Use D.O.T airline & fittings.
I've been getting DOT airline from McMaster Carr. For fittings, I get them wherever is easiest as long as they're DOT rated. The only fittings on my dually that aren't DOT are the 1/8" 'T' splitters for the pressure gauges (apparently nobody makes them). I did pretty good for the first 3yrs. No leaks or leak-downs. Then, a line split @ the paddle valve for my drivers front. It was a quick easy repair once I could stop to get it done. I now have a leak-down between the tank & the valves for the rears I've been ignoring (it's a PITA getting underneath it to ID the 'where' so for now the rear pump just works harder than normal after it sits for a few days).

Do you use any sealant or anything to lock them in place on the PTC fittings? I've read of different sealants they use, but never for Air Ride. Side note - I'm looking at a 89 Single Cab Dually this weekend, I hope I can bring it home. |
