The female foster fitting on my fill rig, (ebay model) broke after a couple years. I am trying to replace but my AV fitting (PA) WON' T thread on. It seems to be the same dia. Are there different pitches on hpa fittings?
Yes there are different thread pitches and a lot of them look very close to the same. Be more specific with what your fill source is and I’m sure someone with the knowledge will chime in.
The threads on my Vevor (Chinese) compressor fittings are M10x1 and I had to buy an adapter to use my microbore hose with it (1/8bsp).
Keyman, I have one of the brass female foster fittings that I took off my Vevor fill hose if you want it. I'll never use it because I always put the microbore hose on whatever fill source I'm using.
