Below Water line fittings

[ontherocks83]

On the boat I just purchased, this is the T-fitting for the head inlet and sink discharge thru hull. It says PVC on the greyish blue fitting which I am pretty sure is a no no. Problem is I can't seem to find any below waterline T-fittings online. Does anyone know a good source to get fittings other than just elbows, reducers, and hose to hose barbs?

As usual thank you in advance for any help!

Hamilton Marine has them in bronze.Then you can screw in marelon tapered thread adapters,also Hamilton marine.

I'd also replace that non-braided hose and certainly use better quality SS hose clamps. Also, not thrilled with the actual hull penetration, no backing plate and it almost looks plastic.
