All of a sudden the buna 113 o rings in the c02 cap have started to swell..I know this was common in other materials...but didn't think these swelled ...any opinions ...thanks

Ps..anybody got a McMaster carr poly number...

I was very pleased with my last order from the oring store. Prices were cheaper than Carr too, at least for the sizes I purchased...shipping was $5 and change.
