D-D U.V thread size | D-D The Aquarium Solution

Hi, I have the 80w UV plumbed directly into my return in my 700 liter reef aquarium. My plumbing is 1" but the hose connectors in the UV are much smaller in diameter, which results in significant strangling of the return and reduced flow. I would like to use unions and plumb straight with pvc pipe. Would you be so kind as to advise what type of union thread would work on these units?


Many thanks


Kind regards

The male threads on the Deltec U.V systems are 3/4 BSP, to convert you will need to either find an all in one type hose tail connector at your fish store or use the correct solvent weld fittings to convert over to either hard pipe or a hose tail conversion for your soft pipe.
Best regards Tony
