A second life for low pressure seats

[Kupu]

I have flipped a fair share of puck style seats to get double life out of them. There was a time when it was out of necessity, not knowing where to buy or how to punch seats. Now it is just a habit that is hard to break.

The seat tables shared by Couv in post #9 are a good resource. Here is a version updated to show options for Poseidon Cyklon and Scubapro D-series and AIR1.

Very useful guys. Thank you very much. I see in the list that there is no standard size but the differences may be small enough in many cases.

Thank you to all who make this wonderful resource available, and to all the thoughtful contributors.

Magnificent!

I was taught during my PADI equipment specialist instructor course to flip the seats if you can (1st stage too). I like others here have considered the materials, punching them. So I'll be exploring those ideas and links here thanks guys.

Something else I've done is to take a lighter/flame with the high pressure seat in the piston in a first stage, and remelted just the top to make the surface smooth, self-level and flat again and fill in the impressions. So far no leaks and I'm still alive.

Here we only have access to nitrox 32% (usually 31%) that is made with a membrane filter. So not super worried about O2 compatibility. Of course if I ever used partial pressure blending or took it where that's done this would be a different more oxygen safe approach with replacing everything with oxygen compatible parts and clean it for oxygen.

I know this is an older post but I appreciate others are already ahead of me innovating. Thanks for the ideas!
