Without anything for reference in terms of size all I can do is speculate.
My best guess is 3/8" or 1/2" NPT.
Take that bag back and go buy yourself a real one.
You don't like TRP?
I got it from a family member who works at Pete, so that prolly why.
By chance do you guys got a part number for the steel bracket that’s on top of the bag?
Most likely 1/2 npt but I have seen a few with a 3/8 npt, it looks like a 1/2”
TRP = Temporary Replacement Parts
Peterbilt dealerships sell a lot of TRP products so I just always assumed they were a good brand.
TRP air bags are Conti-tech, quality product. Some TRP products are good, some are not so good. TRP brakes are know Meritor.
