My Gas Problems Continue

All you engineers, speak up.

I keep having gas leakage problems. And I don't mean the usual kind. I mean in my beer kegs.

I have this idea that it's because I need to put fresh O-rings in the tops of the kegs every time I fill them. I think maybe the O-rings get deformed while they're in the kegs and I should rotate them so they have time to expand again.

Is that standard O-ring practice? This is not really my field.
