Nice Smiley.....make 'em 8" and u have a winner! If I get one, you can use it to make your molds.
I think you guys are just making crap up.
CO2 can impregnate buna, causing it to swell. Which increases friction between the ring and the surface it seals against considerably. Which can cause it to wear out at a faster rate, or break. To solve the problem, use Viton.
