Glass holes bulkhead size?

[b4tn]

Sounds stupid. But I have a glass holes 1500 overflow and return kit. I had it installed for 4 years and recently broke down my reef to move. I want to replace the gaskets as I’m putting it back together but I don’t remember what size bulkheads it used for both the return and the overflow or if I should get ABS gaskets or schedule 80 gaskets. Anyone have the kit that remembers the sizes? I think it’s 1 1/2” for the overflows and 3/4” for the returns

Here’s a size chart that may help.

Yes, tthat helps thanks. I can measure the bulk heads to figure out what size I have.

Also, for anyone else that may stumble on this thread. I found the difference between a schedule 80 and ABS bulkhead.

You are in need of a bulkhead/gaskets that fit a 2 5/8 inch hole. That bulkhead fits 1 1/2 inch pipe.

Thanks, I guessed correct Do you happen to know the size of the bulkhead they shipped with the return? I think its 3/4"

I never did the drilled returns....actually weren't available from GH back in the day. I went over the top. If I were to guess, I'd say to fit 3/4 pipe.

I'm still running a glass-holes 1500 overflow & return and yes, the return bulkheads are 3/4".
