Midland Industries 444024 Fire Hose Hex Adapter 1-1/2 in Brass

Product Description

The MIDLAND INDUSTRIES 444024 is a female-to-male hex adapter designed for fire hose connections. It accepts a 1-1/2-inch Female NPSH inlet and transitions to a 1-1/2-inch Male NST outlet, allowing connection between hose fittings that use different thread standards. The adapter is machined from brass, which provides corrosion resistance and durability under the demanding conditions of fire suppression and water supply applications. The hex body allows for wrench engagement during installation and removal. This fitting is intended for use by fire protection contractors, municipal fire departments, and trained service technicians working on fire hose assemblies.

The 444024 is used in fire hose systems where a Female NPSH thread must couple to a Male NST thread. NPSH and NST are both common fire hose thread standards, and mismatches between them occur frequently when integrating equipment from different manufacturers or updating older hose assemblies. This adapter bridges that gap in a single compact fitting. It is appropriate for residential and commercial fire protection systems, standpipe connections, and fire department supply lines wherever a direct NPSH-to-NST transition is required.

Installation Notes

Installation should be performed by a licensed fire protection contractor or qualified technician familiar with NFPA standards and local fire code requirements. Shut off and depressurize the water supply line before removing or installing any hose fittings. Apply thread sealant appropriate for potable or fire suppression water systems as required. Do not over-tighten; use the hex body with a fitting wrench to achieve a secure, leak-free connection without damaging the threads.
