Response to QB 79 valve O-Ring
the major o ring suppliers their first choice of o ring material for co2 both gas and liquid is Buna (nitrile).
The problem is most hardware stores etc. carry Chinese assorted o rings, which are junk. I've found that U.S made Mil Spec Buna is the best for co2 and it doesn't saturate, and lasts for years.
