Where to get green Delrin for machining into O rings for HW piston or can I buy Delrin O rings
and when looking on You tube it always seems to be green.Why ?
Ok maybe o ring was the wrong wording it is for machining around the outside of piston for a better fit in the air chamber
Are you thinking of Oilion bar , a self lubricating plastic. It's green.
The word Delrin seems to crop up but open to advice

Delrin is Dupont's name for acetal h which is a homopolymer don't buy copolymer as it's to soft.
other names to search for are acetal and hdpe (high density poly ethylene)

I'd 2nd 2 200's comments - I found the same - very high speed required to turn smooth - and no noticeable difference from delrin
I thought the bearing rings were made from PTFE ?
Delrin has good abrasion resistance and rigidity, once installed it's good for many thousand shots, PTFE is a bugger to swell with age and expand with temp, add to which delrin/acetal is easily available and quite cheap.
