Are these Bulkheads good?

[vishwa.J]

I had a tank with schedule 80 bulkheads, wont do that ever again. They are huge, both taking up space in the tank and the require larger holes than their ABS counterparts. There really is no reason to use Sch 80 in an aquarium application, we never experience the pressure that would require them.

If someone is cracking the ABS bulkheads they are using them incorrectly. You should have no issues with ABS on 12 mm glass.

Thank you! that was helpful..
I just like the rough look of them

I glued by pvc directly to my abs bulkheads. (Slipxslip)

There is what's called a "transition glue" which bonds pvc to abs, but from what I read regular pvc glue makes a good enough bond for these types of low pressure applications.

Just throwing that out there

Yeah Normal PVC glue will be enough I think
cause I haven't glued at all in my current tank and it doesn't leak..
