Look like the main o-ring is a -030. I've ordered a few extra if anyone wants one.
I found an o-ring for the rear seal in my parts bin that fits so not sure the size.
Sometimes I impress even myself.
Sent you an email. Let me know if you don't get it. Need your snail mail address.Greg Barlow wrote: ↑Wed Sep 11, 2019 4:30 pmMark,
I have one of the gauges marked as a Scubapro. I’d like to have one of the o-rings if you don’t mind. My email is [email protected].
Thanks for all of the great information.

Thanks Couv!. I don't quite know why I became fascinated with these type gauges but once I get an itch.....
Greg, anything is possible in love, war and vintage scuba gear. I simply printed out an o-ring chart and laid the old o-ring on various circles until I found one that fit (ID, OD, CS = -011). I also took calipers to the o-ring groove and that size matched the ID of the -011. Doesn't mean its not the other size though. If it blows up in your face, then I was wrong. Use your own discretion.

As I’ll be tackling my own gauge soon, I was wondering about the possibility.
A number of vintage regulators actually used a -903 for LP and HP glands rather than a -011. This is particularly true with the Voit models. While a -011 works, it is typically more of a crush fit.

Thanks for the great information.

Thanks.
