Good morning!

I replaced that valve diaphragm with Viton 60 sheet material I sourced from eBay.

The material came in a 3 pack 6" X 6" X 5/64" (.0781"). 1 piece each of Viton 60, 70 and 90 durometer.

I selected the 60 because it had the flexibility that the diaphragm needed and sealed perfectly.

I have had it installed for several years with out any leaking or other problems.

I don’t remember what I paid for it but it is basically scrap material left over from

some manufacturing process so it wasn’t much.

Hope it helps you!

Respectfully,

Bob
