It's an old field rental Mayhem (aka F.R.O.G). I'll dig mine out of the closet and get some measurements in a bit.

Delrin poppets have a 110 o-ring on it
As for the large oring, it is in the wrong location in the manual. It goes behind the bolt as a bumper when the bolt slams back into the valve body. If you swap the bolt or valve body oring just toss the old one in there for a bumper.

The bodies do separate a bit when you air up since there's only one anchor point for the breach.
