what size bulkhead fitting for 63MM hole?

[Pokerman11]

I have a 63mm hole saw from an older project.

I just used the saw on a fuge tank I'm building, but I can't remember for sure what size bulkhead fitting to use. I'm thinking this is 1 1/2 inch ABS - or Schedule 40.

Anybody got the specs on bulkhead hole sizes for both ABS and Sch 40?

Thanks but that chart seems off for max hole size. For example I have some 1" ABS bulkheads. The chart has max for 1" at 68mm - but that's WAY too big. The entire fitting is not 68MM in diameter.

I usually only pay attention to the minimum hole size since I don't like a lot of free space around the bulkhead.

All of them are different...3 different manufacturers will all have different sizes for same bulkhead

Hi

Usually 63mm is a 2" fitting. At least it is the OD of a 2" pipe
