Although I know viton are supposed to be more durable, my understanding is they are a bit of overkill for scuba, especially if you service your gear regularly. And then there is the point brought up by Bama that they get kinda toxic when they go poof.Originally Posted by iDiveChick
I prefer fluoropolymer elastomers such as Viton.
Amtrosie, isn't it true that viton is not the common material for o-rings in aircraft applications, even in the presence of 100% O2? I thought I read that it is more common to see EPDM?
