Nova liberty o rings

[Bluecup]

Hello AGN,

I need some help finding the metric PU (polyurethane) O rings for the ati Nova Liberty 22. I have all the 90 duro meter and the 70 duro meter coming on Friday. I had to order multiples of each and will have some extra's if anyone needs one of something P.M.. me and I will see if I can get it to you.

Thank you,

Jim

Are the ones you’re seeking for a location exposed to abrasion? That is the only property of polyurethane that is useful for PCP use and generally the only spot on most PCP’s where that’s true is the bolt or breech O-ring. And indeed, metric polyurethane O-rings aren’t so easy to find and they tend to be comparatively expensive. So if you were seeking them to use in static locations, save yourself the headache and expense and use Buna-N instead. They’ll last longer too.
