Sterling Pump O-Rings
I've done some reading and this is what sizes I found for the Sterling Pump, these are the same sizes I have in my marker. Now, I'm not to sure of the Durometer so this is just for sizes:
part dimensions part number
Bolt 7/16 I.D. X 1/2" O.D. X 3/32 thickness 111/70
Valve Guide/ 1/2" I.D. X 5/8" O.D. X 1/16 thickness 014
