Many people have no issues using the supplied (and flat) bulkhead from MistKing on the rounded wall of a plastic 5 gallon bucket. I’m sure if you screw it on tight enough, the plastic bucket and bulkhead flexes enough to make a good seal. Still, some people have experienced drips and leaks but get around it by using silicone on the bulkhead. So I wondered, why not use a square bucket with flat walls?
