Aqua UV union size

[BaldAndBeard]

I'm looking at ordering an Aqua UV 57w sterilizer. My install however makes it so I will need to swap the 3/4" barbs for the inlet/outlet with a 90 degree one. I'm just not sure the thread size where this screws into the UV body itself. Would like to get everything ordered up front without having to wait for it to come to measure what I need.

Anyone have one of these that can tell me the thread size? Looks like maybe 3/4" or 1" but cannot find any info to verify.

I beleive the 57w came with the option of 2" unions and then 3/4" reducing bushings. So you would just need a 3/4" mip x hose barb

The threaded male adapter should be 3/4 as well.
