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
Donkey Body

Started with a Splatmaster, moved onto a Nelspot 007, then came the Autocockers, then a STERLING Pump, next was a Bob Long defiant then a PM7. As of now I have 10 Sterling Pumps, 2 Phantoms for SC, a CCM SS-25, a PGP and a Sovereign 3.
