I don't have the valves any more so I can't cross the part that I used (20 years ago).
Ltstanfo, can you measure the outer diameter of the recess for the nylon washer? If I remember correctly, it was about 3/4" but I need it more precisely. Also, is there a stub sticking out the middle? What is it's diameter.
The part that I found was a metal/rubber bonded seal that was practically blowout proof. I also used it to put regular SCUBA yoke regulators on Medical post valves.
