Sheridan PMI II valve seal

[Heavy_D]

Does anyone know where to source the proper seal, or know the proper size Oring to Use for the Valve Face seal? Was leaking down barrel fairly bad, and the Valve face seal was Fubar...

Cheers!

They aren't orings. . It's a flat disc crimped into the brass housing

You can use Cocker cup seals if they're easier to get, otherwise you get any 12gram cupseal and cut the piercepin off.

10-4 threw in a cocker Cupseal/stem and she's back In Business

You can get a new stem from pgpjunkies website. Just cut the pierce pin off.

I've used iring with good success before, I need to check my notes if you want details 😅

I have a bunch of old stems with bad seals, Id love to know the oring size

I've got a couple stems I've crammed some 010-90 urethane orings into, just need to test them out. I had some success with buna orings but they eventually squirmed out - I suspect they didn't like 12gram usage.

009 might fit better, 010 is all I have on hand at the moment - in urethane, anyways.
