Standard Threaded Bulkhead Fittings 1/2" Color: Black
This bulkhead was exactly what I needed for my aquarium. Its threads allow its use with PVC tubing available at a hardware store. I used some Teflon tape, andI had no problems with leaks.
It did not fit perfectly into the 1-1/8" hole I drilled at first, but after I enlarged the hole slightly by pushing the hole saw against the sides, it fit well.
