need help figuring size of bulkheads

[bovsbaitboxes]

I have 2 tanks I need bulkheads for and I want to buy through the group buy the holes in one tank are 1 3/4" and in the other they are 1 1/2" what size do I get ??? (through premium aquatics) thanks John

¾ inch standard bulkhead needs an 1 ½ hole  (if schedule 80, 1 5/8 hole)
1 inch standard bulkhead needs 1 ¾ (if schedule 80, 1 7/8 hole)


By appearance they look like standard bulkheads at Premium Aquatics.  I'll ask PA and double check that they are "standard" bulkheads.


EDIT TO ADD: Actually looking at the price I'd almost guarantee that they are "standard."

Here's the word for Premium Aquatics:


All of our regular bulkheads are sch 40, so the ¾ and 1” would be fine. We do have Sch 80, but they are marked 80 and expensive, the 40s are the 5 dollar ish ones.
