The AQUALINE FP-HA15F75H is a brass fire adapter designed to connect a 1.5-inch Female National Standard Thread (FNST) inlet to a 0.75-inch Male Hose Thread (MHT) outlet. Built from brass for corrosion resistance and durability, this adapter serves as a critical transition fitting in fire protection and water supply applications. It is typically installed by licensed fire protection contractors, plumbers, or irrigation professionals working with hose connections, standpipe systems, or fire suppression supply lines. The threaded configuration allows for a secure, leak-resistant connection between differently sized threaded ports.
This adapter is suited for use in residential and light commercial fire protection piping, hose bib connections, and similar water distribution setups where a size and thread-type transition is required. The 1.5-inch FNST side accepts standard fire hose couplings, while the 0.75-inch MHT side connects to standard garden-style or utility hose fittings. It is a practical fitting for system tie-ins, testing connections, and auxiliary water access points.
Designed as a standard-thread fire adapter for use with 1.5-inch FNST female connections and 0.75-inch MHT male hose thread fittings in fire protection and water supply piping.
Installation should be performed by a licensed plumber or fire protection contractor in accordance with applicable local codes and NFPA standards. Shut off the water supply and depressurize the line before making or breaking any threaded connections. Use thread sealant tape or compound rated for potable water and fire protection service on all threaded joints. Do not overtighten brass fittings, as this can crack or distort the threads.
