Trailer air supply valve

[Csm Davis]

Does anyone know who built the stock valves like this one? Would like a rebuild kit for it.


I have already replaced it with a new civilian one, but would like to rebuild the original.

Got a part number?

I am not sure specifically on that valve but everything I have needed is midland now haldex civy air brake parts on my m923.
Typically have a casting number or parts tag from haldex typically with n or kn prefix. Numbers usually cross easily on their website with parts listed if available.
Bendix parts also usually easy to cross reference also.

Got nothing on it, guess I may need to dig out the PARTS TM

Okay it's a PP-7 but still don't know exactly which manufacturer or part number.

A pp7 is a bendix product. Pretty common valve.

It is out there new and rebuilt. I see Amazon has a new clone no name under $30

I don't see a rebuild kit though by Bendix.

Truck pro or Napa should stock.

Search pp7 on ebay gives you a ton of listings.
Just make sure same ports as yours.

See attatched info on pp7 from Bendix

Yeah seams like everyone uses bendix nomenclature to describe the valves out there. But what's odd is the smart guy at the parts house that doesn't live by what the computer says gave me a pp1 because I only use have 2 lines going to my valve and said doesn't need a pp7 and I believe that he is correct.

Could be a case of the military needing a lot of PP7 valves, and the PP7 can also be used in equipment where a PP1 might work. Logistics always plays a role. In the power generation arena, we use the same parts in different applications, where it would have been a possibility to use something different. Saves big bucks and cuts down on the amount of parts needed to be stocked.
