what size bung fits a 2 inch hole?

Bondo on Mar 15, 2016

BEST ANSWER: I don't know whether or not your speaking about an actual 2" hole or a nominal sized 2" hole, threaded or unthreaded. Generally a 2" hole has a range between 2" thru 2 5/16". So my best advice to cover the range would be to find a tapered bung with a small diameter of 1 7/8" up to a large diameter of 2 1/2".

Hi Mark, a 2" opening is slightly larger than a standard carboy. The #10 1/2 might work, but the top diameter is only 2 1/16". For best results, measure the diameter of the mouth of your carboy or fermenter and compare to rubber stopper measurements to find a good fit. Hope that helps! Cheers!
