Description
This specialized pump union fitting features a 1-1/2" female buttress thread connection with an interior diameter measuring approximately 2 3/8" on one end. The opposite end is a street spigot designed to be solvent-welded into a 1-1/2" fitting, with an outer diameter of 1 7/8". This complete half union is specifically engineered for certain spa pump configurations and differs from the commonly used standard 1-1/2" Threaded x 1-1/2" Slip union found on most hot tub installations. Verify your existing union dimensions before ordering to ensure proper fit.
