Best Choice for Rubber Diaphragm
(OP)
Can someone tell me if and why peroxide cured EPDM is the best choice for the diaphragm material for a low pressure hydrogen regulator.

Most materials are permeable to hydrogen. But at low pressures, EPDM is probably good enough. All depends on how "low" is "low" in your case.

If you have the thickness of the diaphragm and the permeability you can calculate the rate of permeation. Probably not enough to worry about, provided the regulator is designed to vent any diaphragm leakage. But then again, what happens should you ever have a diaphragm failure?
