Where to find a replacement part for my airgun

Question

My Crosman S1008 is no longer working. Every time I put a CO2 cartridge in it, it leaks. I cant even get one shot off before the cartridge is empty. So I took it apart and found that the O-ring is cracked. I tried to find parts but ive had no luck. The gun is more than a year old so I cant send it to the Crosman to get it repaired.

Does anybody know where I can get a new O-ring?

Answer 1

You can buy orings at the hardware store, etc.   You just need to get the right size.
