1 Inch PVC Union Coupling, Fits 1.315" OD SCH 40 PVC Pipe

WHY SEVENJUNGLE This 1 inch PVC union is built for homeowners and DIYers who need a plumbing fitting they can trust under real pressure. Each union is rated for 145 to 232 PSI working pressure on Schedule 40 walls, so it holds up on pool pumps, well systems, and sprinkler lines without the thin wall burst risk found on economy fittings. WHAT YOU GET Two 1 inch socket x socket slip joint unions with built-in EPDM O-rings for a water-tight seal. No Teflon tape required, the rubber gasket does the sealing. White PVC resists UV, corrosion, and humidity for years of indoor and outdoor use. INSTALLATION Apply standard PVC glue to the socket ends, insert your 1 inch Schedule 40 pipe (1.315 inch outer diameter), then hand tighten the union nut. The detachable design lets you disconnect and reconnect without cutting pipe, perfect for seasonal pool and sprinkler service. WHERE TO USE Pool pumps, well tanks, sprinkler manifolds, sediment filters, water softeners, and general cold water plumbing. Measure your pipe outer diameter before ordering to ensure a correct fit.

• PRESSURE RATED 145-232 PSI: This Schedule 40 PVC union handles 145 to 232 PSI working pressure. Unlike thinner economy fittings, it holds up on pool pumps, well systems, and sprinkler lines without the burst risk you worry about on your main water supply.
• LEAK-FREE EPDM O-RING SEAL: Each union has a built-in EPDM O-ring that presses tight for a water-tight seal, no Teflon tape needed. The rubber gasket does the sealing so irrigation, pool, and plumbing connections stay drip free for years.
• DETACHABLE DESIGN FOR EASY REPAIR: Unlike permanent couplings, this union lets you disconnect and reconnect pipes without cutting. Ideal for pool pumps, well tanks, and sprinkler manifolds that need seasonal service. Glue the socket ends, then hand tighten the nut.
• SIZE WITH CONFIDENCE: Fits standard 1 inch Schedule 40 PVC pipe with a 1.315 inch outer diameter. This is a socket x socket slip joint union, not a threaded fitting. Measure your pipe outer diameter before ordering to avoid a wrong or loose fit.
• 2 PACK VALUE, CORROSION RESISTANT: Premium PVC resists UV, corrosion, and humidity for long indoor and outdoor use. Two unions cover a full repair job or a multi zone project at a fraction of big box store cost. White finish matches standard PVC plumbing.
