Found these digging through some parts for a job I used to work. They say Foster on them and are probably 1/8" or 1/ 4" pipe thread. Are these the same female Foster fittings used for PCP airguns?
Thanks

they may look the same but they may not be rated for the same psi. unless you know what psi they ared rated for i would not risk it personally.

I'll have to give one a closer look for rating and/ or part number to research.

Hard to tell from that photo, but if I had to guess, I would guess that they are made for shop air use, about 100-150 psi and the threads on them are 1/4" NPT.... In any case, the fact they are brass to me is a dead giveaway that they are NOT suitable for HPA use.... Find a part number, and look them up in the Foster catalogue to get a pressure rating....

odd considering ninjas brass fosters are 3000 psi rated, as is the foster I use on my hill. I would research part numbers to find the pressure rating, but just because its brass don't mean its no good....

Correct, but it does mean you should be careful and check the part numbers (you should even for steel).... Also, a some parts of a female Foster in brass may be OK while a male is a no-go as the steel balls in the female that hold it in place will dig into the shoulder on the male and can cause failure.... I have personally seen this happen.... Ninja's male Fosters are hardened steel....

On female fosters brass coupler cover is ok but the main body(the part that is threaded)must be steel. The units pictured are not HP rated. I personally use the 6000/9000 psi rated units. If you have seen what happens when one fails you will also.

Yep, these are a no go. Model 2202 says something like 150PSI. Darn.

this has me curious as the main body of mine is brass, it was $30 directly from a high end arigun manufacturer, why would they risk it?
