Description
Achieve a watertight, professional-grade plumbing connection on your Pentair SuperFlo or SuperMax pump with the Swimables SW-21-350 Union Kit. Serving as a direct stand-in for Pentair part 350157, this kit ships with two unions featuring a 1.5-inch internal slip and a 2-inch external slip, along with matching adaptors, threaded nuts, and fresh O-rings. Every piece is precision-molded to match factory tolerances, so you get a solid, drip-free seal that keeps water flowing at full volume through your circulation system.
