Hi, thanks for the Chart (many years ago). But as I saw on ScubaGaskets; that they sell the EPDM o-rings in a package that all seem to be 70 Shore. Whereas you have written in Red "70 Shore" for just 2 of the O-rings; so are the rest all meant to be 80 Shore? Or does 7o apply to the list below where you wrote 70 shore? It is often difficult to fing 80 shore; so is 70 or 75 acceptable? What if I can get Viton o-rings instead; should they be 85 Shore...because I have often seen 85 offered as an option instead.
