Midland Industries 444113 Fire Hose Male Swivel Adapter

Product Description

The MIDLAND INDUSTRIES 444113 is a brass fire hose male swivel adapter with lugs, designed to connect fire hose assemblies to threaded pipe or valve outlets in fire suppression and standpipe systems. It features a 2-1/2 inch female NST swivel inlet and a 3 inch male NPT outlet, allowing a standard fire hose coupling to mate with a larger NPT-threaded fitting. The swivel design permits hose rotation without kinking or twisting the connection. The integral lugs provide a secure grip for hand-tightening and spanner wrench engagement. Brass construction resists corrosion and delivers reliable performance in wet-system fire protection applications. This adapter is handled and installed by licensed fire protection contractors and plumbing professionals.

This adapter is used in commercial and industrial fire protection systems where a fire hose connection must transition from a 2-1/2 inch NST swivel coupling to a 3 inch NPT threaded pipe or outlet. Typical applications include standpipe risers, fire department connections, hose cabinet outlets, and valve assemblies. Its lugged swivel design is well-suited to locations where hose lines must be connected and disconnected frequently during testing, maintenance, or emergency response operations.

Installation Notes

Installation should be performed by a licensed fire protection contractor or plumber in accordance with NFPA 14, the applicable building code, and local authority having jurisdiction requirements. Shut off system pressure and depressurize the line before removing or installing any fittings. Use a spanner wrench on the lugs and a pipe wrench on the NPT threads to achieve a proper seal. Apply an approved thread sealant to the male NPT threads only; do not apply sealant to the NST swivel seat or swivel threads.
