Two stage Diaphragm, for Voit or US Divers GRAY or BLACK

This silicone diaphragm is perhaps the last you will ever have to buy. Silicone will out last any other rubber products out there. I do not need to tell you Voit lovers what OEM gray diaphragms are like today. These work great in you 2 stage DA Aquamaster, Royal Aquamaster, and Voit Navy. It can also be adapted to use in some if not all single stage US Divers and Voit. You are buying one diaphragm and you must choose a colour.
