Well….I placed my order thru Grainger today. Their part Number #1DPZ3. A 12" square of the Buna-N/Nitrile rubber sells for $4.24….shipped to a store for free. I figure I can make as many as 12 diaphragms from that 12 x 12 sheet ….so it’s worth a try.
They sell a variety of Nitrile materials…..they differ in hardness. elongation , and various other factors. I’m hoping that the one I picked will work ok.
We’ll see.
