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.
