Product overview
The Half Union Adapter, 2-Inch, for Sta-Rite Pool or Spa (2-Pack) is an aftermarket union / fitting built to replace the original component in Pentair equipment-pad plumbing. In service it connects sections of plumbing and allows equipment to be removed without cutting pipe. Replacement is routine: the nut threads strip and the seat distorts, so the joint can no longer be sealed by hand. Ours is molded in PVC / reinforced thermoplastic.
