Accurate 3/4 Inch PVC Union Fit: Includes 10 pieces of 3/4 inch PVC union pipe fittings for replacing fixed joints or adding removable pipe connections. Designed to fit standard 3/4" Schedule 40 PVC pipe with 1.05" outside diameter. Please check your pipe outside diameter before ordering. Leak-Resistant O-Ring Seal: Each PVC union coupling includes a built-in EPDM O-ring gasket to help create a tight, reliable seal at the union joint. The gasket design helps reduce the need for extra sealing tape when properly installed, making the pipe connection cleaner, easier to assemble, and easier to service later. Removable Union Design for Easy Maintenance: Unlike fixed pipe couplings, this PVC connector allows two pipe sections to be connected, separated, cleaned, inspected, or replaced more conveniently. It helps save time during future pipe repairs, pump maintenance, filter cleaning, system upgrades, or seasonal disassembly. Smooth Threaded Nut for Easy Matching: The union nut features clean threading for easier tightening and loosening during installation or maintenance. This 3/4 inch PVC union coupling helps provide a secure matching connection while still allowing the fitting to be removed when you need to access valves, pumps, filters, or pipe sections.
