Bulkhead fittings help!

[reefnoob123]

I have a 55 gallon "reef-ready" tank and i need to determine which size bulkhead I need. The smaller hole in the overflow is 1/2 inches and the large one is 1 and 3/4 of an inch. What are the correct bulkhead sizes I need to fit the holes in my tank perfectly?

Well the 1-3/4" hole should be for a 1" bulkhead.
But I'm a little thrown off by the 1/2" hole. Are you sure this is correct?

 

[reefnoob123]

Lol it's a 1 and a 1/2 inch. My bad.

Sounds like you're looking for a standard, Schedule 40...3/4" and 1" bulkhead to me.

3/4's for for the 1.5 inch?

Yep. If you look around for Sch 40 bulkheads online they usually tell you what hole size you need for a given size bulkhead. 3/4" sch 40 requires a 1-1/2" hole. 1" requires a 1-3/4" hole.

I am obviously a noob at this so.. Is a sch 40 a standard bulkhead?

Sch 40 is standard sizing for pvc pipe and fittings. Sch 80 is heavy duty stuff and the sch 80 bulkheads require a slightly larger hole than the sch 40 stuff. You just need standard sch 40 bulkheads.

No, if you look at the top of the page is says Schedule 80, Heavy Duty. They won't fit your tank unless you enlarged the holes. Search for some Sch 40 fittings.
