Foster Fitting Specification

[lindsey]

When people refer to the "foster" fitting is the true specification the ZSi- Foster FST fittings?

This 12MP looks very close to what is used.(at least on the QD side)

Part of this is curiosity and part of it is I don't trust the stuff I see on some online sites.

BTW look at the pressure rating of a 1/8" Size Mated with a brass Socket. Lets be glad its 4:1 safety factor.

Thanks,

All I know is that I have a few so called "foster" fittings, that don't like one another. Some fit right, some very tight, some very loose. Just like all the different threads used on the whips and associated fittings. Major pain in the rear.
