Product Overview

The Pentair 523148 Union Assembly Kit is a service replacement part used in the plumbing connection assembly of compatible BioShield UV disinfection systems. Pentair replacement parts materials identify this part specifically as the union assembly for models 522638 and 522945, and current seller references also describe it as the 3 inch BioShield union kit for those same systems.

This kit is well suited for repair or maintenance situations where the UV vessel remains serviceable but the original union connection has become worn, damaged, or no longer seals correctly.
