ScubaPro MK11, R395 and R295 service manuals

Can anybody tell what is the purpose of the thin teflon-like shim between the cap and the membrane holder in R295? I kind of ruined one on a regulator bought from ebay. The whole regulator had a nasty mold odor that wouldn't go away, so I finally resorted to immersing the parts in boiling-hot water with dish soap and sodium bicarbonate. While the rest of the parts behaved, the thin white shim warped instantly.
Is it just a friction-reduction thingy that one can live without, can I cut another one from a thin PE sheet? And also, what can I do to get rid of the smell, because now it's basically unusable.

A photo of what you're taking about would be helpful. I'm afraid from your description I do not know what you are talking about.

That would be the warped white ring.

That looks to be a diaphragm friction ring, in which case you need it.

Then I guess I'll reheat it and persuade it back to straightish. Thank you! Also, may I dare DM you about the service manual and schematics for this thingy?

You may dare.
