Yes, they are steel and sharp too. You're not going to reuse that 0-ring, are you? If you don't have chrome in the slot or don't feel you have the dexterity, then just spear the o-ring. I've yet to cause a leak that way, but I have more experience than most dealing with o-rings. I was a tech on a super-con magnet in college. The clearances and seals in Scuba are pretty 'loose', if you catch my drift.

As for the in hose tuner, www.ScubaTools.com has them, but when you learn the trick of how to set up that second stage before you put any pressure to it, you'll find it to be just another weight in the toolbox. I have a lot of paperweights that looked useful when I bought them. Before a lure catches any fish, it has to catch the fisherman first.

My workshop is always open to any instructor who wants to use it: no charge.

Hello from Brazil!!!

The lighter spring means that during storage there is not a strong force acting, so the seat is degrading more slowly.
But the great advantage of a balanced second is that it will work well over a range of IP values...

Way back when, Scubapro provided a blue plastic spacer to relieve spring pressure during storage. There is still one attached to one of my 109s.

Older Sherwood second stages have a pin next to the purge button that you can press in to do the same thing.

i am working on a scubapro mark V first stage. . There are no shims for the piston. Intermediate pressure is about 150. I would think shims by compressing the spring might increase Intermediate pressure. since IP is about 150 without shim. is this an ok pressure, and if not, how do I chanke the IP?

from the MK-5 service manual:

Also, in days gone by, there were different height seats.....
