Wondering if anyone has had the opportunity to remove the pressure from the gauge assembly? I know I need to chuck up a socket in the lathe but I'm not sure what size fits the gauge itself, any and all help is greatly appreciated. Thanks everyone!

Thanks guys! I was guessing 7/8 but thought since this rifle is from Europe it would be metric. I'm not sure if I'm just going to allow the gauge to be sealed by just an oring, I might use some 'masters pro dope' to ensure I have no leaks now or later.

I'm gonna step out and say your gauge is busted. Mine seamed like a leak too, but it was the gauge. Thats why we cut it open to see how it was made.

Great news! That means all my gauges are probably busted! Anyone find any aftermarket upgrades that worked? One thing I can't stand is replacing junk with more junk, I'm a fix it once kind of guy! Thanks

Does anyone know if the gauge is actually a 22mm instead of 7/8? Just figure if it was a 22mm I'd have a little more meat on the socket after I machined it to fit.

I'm figuring its a seal issue thou for one reason, the cylinder wil hold at 150bar. I thought maybe the oring just doesn't have enough compression to hold beyond 150 but this is just my hypothesis. Anyone have on thoughts on this scenario?

Maybe it is the seal. Mine and Castles lost all air. Again, we used a 7/8 and it worked well. Didn't try metric when we had it out. Should have.

Keep use posted.
