Nylon-Reinforced Flat Rubber Seal 1 inch – Reliable Watertight Connections for Pool and Irrigation Systems
This flat sealing washer provides a dependable, leak-free seal in 1 inch threaded fittings commonly found in swimming pool pipework, irrigation manifolds, and greenhouse water distribution systems. Manufactured from black rubber reinforced with a nylon fabric insert, the gasket resists deformation under repeated assembly cycles and maintains its sealing performance across a wide range of operating temperatures and pressures.
The nylon reinforcement layer prevents the rubber from extruding or tearing when fittings are tightened, making this seal particularly well suited to high-cycle applications such as filter housing lids, pump unions, and inline valves that are serviced regularly. At 2 mm thick, the washer seats correctly in standard 1 inch female threaded couplings and unions without requiring excessive torque to achieve a watertight joint. The flat-face geometry ensures full-face contact and uniform compression around the full bore opening.
