Faber valve stem o-ring specs

[whaylonsmithers]

Does anyone know the specs for the o-ring that goes on a Faber valve stem? Size, hardness, material.

http://www.scubaboard.com/forums/tanks-valves-bands/361931-faber-valve-service-kits.html tells me Faber=Blue Steel=SanoSub valves. I guess its a metric size coming form an Italian manufacturer but I'm not fussy if someone knows the Imperial equivalent.

Thanks all for your help.

I never disassembled blue steel valves but all modern valves I have seem take -010 duro 90. I use vitons
