The 2½-inch Swivel Gasket is a replacement sealing gasket specifically designed for 2½-inch fire department connection (FDC) swivels and standpipe outlets. Engineered for dedicated fire protection service, this gasket provides a reliable, leak-resistant seal between the swivel and the mating connection during hydrostatic testing, flow events, and emergency fire department operations.
Manufactured from a durable, fire-system–appropriate elastomer, the 2½-inch swivel gasket compresses uniformly within the swivel housing to prevent water leakage while maintaining proper clearance for smooth swivel rotation. It is compatible with standard 2½-inch swivel assemblies across multiple thread styles—including NST (NH), NYCC, PHX, and Tempe—provided the swivel size is 2½ inches. The thread type governs the swivel’s retention and rotation, while this gasket focuses on sealing at the waterway.
Ideal for fire sprinkler contractors, inspection agencies, and facility maintenance teams, this gasket is a simple yet critical replacement part that helps keep FDCs in service-ready and code-supportive condition. Regular inspection and timely replacement of 2½-inch swivel gaskets help maintain watertight performance, reduce the risk of leaks during testing, and extend the longevity of fire department connection hardware in both new and existing fire protection systems.
