Crosman 600 valve seal material?

[Geoff555]

Hello chaps I have a question for you,please can you tell me the material for the valve seal. I have delryn (rin?), polyurethane and PTFE bar. I have had conflicting advice hence the question. I got some seals for a 160 Crosman from the states and they were made of something that was clear. Don't know what that was, seemed to be soft.
Thank you.
Cheers.
Geoff.

Polyurethane, the colour means nothing as it is just a dye. Basic polyurethane can be almost clear but manufacturers add different colours, red, green, blue etc.,

Sorry Baz, I forgot you also do a lot of work on these pistols.

All the different colour polyurethane O rings below do the same job on the 600.
