Ok I have been using this for years, from Conshelfs to ATXs but I'm a piston guy

I'll compare it to the Fabric-Reinforced EPDM

Actually mostly cloth impregnated neoprene with 100% O2 all, then some more

so have not experimented further, after I scored a few Apeks plastic diaphragms
and I don't have my stuff with me so find that grey plastic fabric stuff and punch

What is it a fabric urethane sandwich blend stuff

Anyway I've not had the rubber sandwich delaminate like that other plastic stuff

When you're on a good thing
