Looking for the ring number for a URETHANE ring for the piercing assembly.

Neither BUNA nor neoprene nor silicone material work for this CO2 application.

Looking for the urethane ring number.

Just got tired of chasing the o-ring store search features.

I think dimensions are 1/2" ID x 11/16" OD x 3/32" CS. That is a 568-112 in silicone, but not the same in urethane. Need urethane number.

TIA

Hi KW, if you're talking about the o-ring that seals to the i.d. of the cartridge housing, then I believe that would be a -113. A -112 has a smaller o.d. than the cartridge itself (.693" vs. .735")... just guessing... don't have an MK.

I use these for my Crosman 600s:

I don't mind spending the extra nickel, leaks take away shooting time... hth
