I think you'll find that all of the American CO2 end seals are the same. The Crosman part number is 150-054 and is easily found under that number on the bay etc. I stocked up on the opaque white ones that are a harder compound which resists any CO2 and holds up to the abrasion from use.
Thanks DT. Although a search of that number only gives this....

Apparently what I saw were a bunch of US listings. In any case, the best way to source common parts like this is to go through one of the major shops in the US like MAC-1, Precision Pellet, etc. They've already gone to the effort of finding the right parts that really work.
Yes we find the maximum number of decent shots is 20 from the 8 grm, and the black rubber seals expand immediately you take off the end cap to put in the new capsule. All my CO2 pistols now have 90 degree Shore A polyurethane seals in as I buy them in bulk. The Crosman 600 seal fits a lot of different pistols, but not the Challenger which is larger.

It looks like I will be writing an article about the Plainsman (Goodenow) pneumatic air rifle soon....
What's the going rate for one?
DT, your bulk fill CO2 Challenger. Is that bulk fill only. Or bulk fill and pump up? Or bulk fill and 8g CO2?
All the best,

I have to say that I am aware of the issues with Buna-N and nitrile o-rings and their expansion when exposed to CO2 but I have been using a Buna-N o-ring as the end cap seal for a few days now with no expansion issues at all. I’ve probably gone through four or five CO2 capsules. I never leave full or partially full CO2 capsules in my guns so they only get used fo a short period before the cap is removed and a new cartridge is fitted. So I think it is entirely possible to use “standard” o-rings on the end cap.
