The 1½-inch Swivel Gasket is a replacement sealing gasket designed specifically for 1½-inch fire department connection (FDC) swivels and hose valve outlets used in standpipe and fire protection systems. This gasket provides a reliable, leak-resistant seal at the waterway, helping to prevent leakage during hydrostatic testing, periodic inspections, and actual fire service use.
Manufactured from a durable elastomer suitable for fire protection applications, the 1½-inch swivel gasket is engineered to compress evenly within the swivel housing, maintaining a tight seal while preserving the clearance needed for smooth swivel rotation. It is compatible with standard 1½-inch swivel assemblies across multiple internal thread styles—including NST (NH), NYCC, PHX, Tempe, and other regional swivel-retention threads—so long as the swivel size is 1½ inches. The gasket itself seals the water side, while the internal thread type governs how the swivel is retained and rotates.
Ideal for fire sprinkler contractors, building engineers, inspectors, and facility maintenance teams, this 1½-inch swivel gasket is a small but essential component in keeping FDCs and hose valves in service-ready, code-supportive condition. Regular inspection and timely replacement of swivel gaskets help maintain watertight performance, reduce leakage during testing, support compliance with fire code and NFPA standards, and extend the overall service life of critical fire protection hardware.
