looking for a 1" and a 1/2" with female threads not glue type. just got through drilling my first hole with a dremel. man it took like 30 mins.

I think Aquabuys probably has them. I also saw some at Optimum last time I was there but not sure if they were threaded or not.

Marine Fish has em, what size do you need?

Saltater city has a bunch in all different sizes

I'd call whomever is closest to you. Most of the stores I have been at have had them.
