So I got the new soldered bulkhead kits from bargain fittings for my keggles. I have a 1/2" punch which makes a 7/8" hole. The hole is slightly bigger than the recommended 13/16" size. Will the slight gap around the bulkhead nipple cause issues with the setup or will it still get tight enough? I would rather punch all the holes instead of using a step bit on them.
I'm debating whether I should use a 7/8" (1/2" conduit) punch or go buy a 13/16" punch. Is it worth the investment for me to pick up a 13/16" punch? What kind of success/leakage are you getting with your 7/8" hole?
