Product overview
Self-Aligning Union, 2-1/2-Inch Slip, Compatible with Waterway — an aftermarket union / fitting dimensioned to drop into Waterway equipment-pad plumbing without modification. 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 and dimensionally checked against an OEM sample before tooling is signed off.
Send us the number stamped on your failed component and we will confirm the match against our fitment records before you order. Sold factory-direct, MOQ 50 pcs, mixed cartons accepted, and OEM packaging available for distributor programs.
