I've recently discovered that my CO2 regulator is leaking out of the adjustment screw hole. I took out the 4 screws, removed the bonnet (as suggested here), and replaced it. The leak now seems to be less severe than it was, but it is still present.

What can I do to fix this leak?

maybe try wrapping some teflon tape on the threads like you do with a natural gas line?


Take the regulator and a 12-pack of beer to a gas supply shop and see if someone there will look it over for you and fix it for beer.
