Scubapro chrome plated brass regulators...

So this look like an upgrade from the Delrin BA 11-195-110 also. I’ll have to find one for fun.

Thanks for sharing.

I found one in a G250 Crystal, they’re not as fun as you imagine.

My Gold has corrosion... why not stainless steel?

Stainless steal is not very stainless. I did find a chrome plated brass one in a G250 though.

Do you know if PN 11.109.109P is chrome plated brass?

I did buy some ones, not original, made by Vintage Double Hose. Stainless steel, till now no sign of corrosion.
Inside a 156 I did buy some years ago there was one of those gold-plated orifices, which was absolutely mint and shining.

I was thinking the gold plating was to help with corrosion, guess not.

I've also rebuilt a few AIR 2 models (3rd gen I think) that had gold plated orifices.

Any idea why they Gold plating?

No. One would think good old chrome plated brass would last longer than gold plating. But my knowledge of plating leaves a lot to be desired. Both methods seem to work well until they don't. ;-)

I knew VDH made orifices for the 109/BA/G250, but I did not know they were stainless steel. If they are indeed stainless, even if they were to corrode, performing Matt Magic/Dr. Singler treatment should solve the issue for a few years until needed again.
