O-ring part number in the manual don’t correspond to anything on the Scubapro O-ring chart. So I don’t know materials, size or SH to cross them over. I thought I saw someone trying to make a chart for the Pilot on SB but can’t find it now.
Pilot orings discussed here, including annotated file for reference. I used EPDM duro 70, except the duro 50 orings where silicone was used.
