Red 4" (102 mm) Nylon Hydrant Cap with Gasket, Loop & Cable protects fire hydrant thread connections against dirt, debris, dust, and ice accumulation. These lightweight, NST-threaded nylon caps have no scrap value, providing a theft-resistant alternative to traditional brass caps.
This 4" (102 mm) Hydrant Cap is made from a fiberglass-reinforced and heat-stabilized polyamide material. This high-performance thermoplastic is specially formulated to provide a lightweight, high-strength replacement for metal parts. It resists damage from UV rays and corrosion, and withstands high and low temperatures without deforming or becoming brittle.
Each lightweight Red cap is threaded with 4" (102 mm) National Standard Thread (NST) and includes a chain loop and cable to secure against loss. Red-colored hydrant caps are used in NFPA 291 systems to indicate that a fire hydrant can supply less than 500 gallons per minute (500 GPM).
