Crosman Crosman blaser 455 help

[Remiel]

Hi, I'm new to this site, I've been trying to find a plastic washer/seal for the crosman blaser 455 and have had no luck, it's part# is 455-001. I have no clue if it's nylon or urethane, but its the last piece I need to restore it back to working condition. I'd even be happy with finding a similar part that works or ideas on a substitute part from another air pistol

the good news is you have the ID, OD and thickness
it looks to be in the 1mm range and i would find some non rubber style urethane and make one
but maybe part 38-094 is the same thing and if so check that and JG has them

I doubt you'll locate an original replacement. Replicate it from a similar-thickness, similar-durometer synthetic material with a paper or leather punch and scissors; perhaps from any number of plastic bottle-caps, Tupperware, credit cards, etc.
