Rage A1 mini reg leak: I'm at my wit's end!

Hello all,

I have recently decided to start plating again. I pulled out my gear and got to work. I did a complete rebuild, with one hiccup: the small exhaust hole on my mini reg housing is bleeding air. I have rebuilt this reg 4 times, or so, and I can not get this bad boy to stop. Any advice would be greatly appreciated.

Check the reg spool and make sure there are no dings or cuts in the o-ring gland. If there are, air can get past the spool o-rings and cause a persistent leak. Usually that leak's going to be caused by the large piston o-ring though. You might want to double check and make sure you've got properly sized o-rings on there.

Thank you for the response. I have changed every o-ring with the rebuild kits I have. The leak is almost free flowing - it's bad.

I'm not sure on it's output, but the reg has the HP mod done.

Are the rebuild kits you're using WDP/APS parts? If not, you might have gotten hold of some off-sized o-rings and it wouldn't hurt to double check the sizes. Did you check on the o-ring glands on the spool (and on the piston, for that matter)?

The more I think about it, I think you're right. I think the large o-ring on the piston is a bastard. The o-rings on the OD of the assm fit too good to have air bleeding thru them.
