Hello, the seal for the 12gm. caplet has crumbled away. It is a light brown but I can no longer tell how hard or soft it should be. Could anyone please tell me what it should be made of, please, so I can try to make a new one. I would be prepared to buy a new valve assembly.
Information on any spares would be appreciated.
Thank you very much.
Cheers.

Polyurethane is ideal for the replacement. Old polyurethane seals used years ago sometimes degrade through bacteria. Think this seal is just a disc with a hole in it, I can post you a piece of flat polyurethane to punch one out.Originally Posted by Geoff555

Thank you all.
Pardon my ignorance but what is a Crosman cart seal? Where could I get one to try please, I have a number of Crosman's so information on any spares supplier would be useful.

Geoff, a lot of CO2 guns use a seal for the end of the CO2 gas cartridge. See the attached pic below.. some others use a sealed gas chamber that uses an O ring.
You may be able to use a standard Umarex cartridge seal as seen in orange in the pic.
