Aqualine FP-HA25F20T Brass Fire Adapter 2.5x2 in Fnst Mipt

Product Description

The AQUALINE FP-HA25F20T is a brass fire adapter designed to connect hose and piping systems at fire protection and water supply points. It features a 2.5-inch Female National Standard Thread (FNST) inlet and a 2-inch Male Iron Pipe Thread (MIPT) outlet, allowing a direct transition between hose coupling and threaded pipe connections. At 1.02 pounds, this adapter is compact and built from brass for corrosion resistance and long service life. It is typically installed by licensed fire protection contractors, plumbers, or municipal water system technicians working on hydrant connections, standpipe systems, or similar fire water supply infrastructure.

This adapter is suited for fire protection applications where a standard 2.5-inch NST hose connection must interface with a 2-inch threaded pipe fitting. Common installation scenarios include fire department connections, hydrant outlet adapters, and water supply transitions in both commercial and municipal systems. The FNST thread pattern conforms to standard fire hose coupling dimensions used across North American fire service equipment.

Key Features

• 2.5-inch FNST inlet accepts standard fire hose couplings
• 2-inch MIPT outlet threads directly onto standard iron pipe fittings
• Brass construction provides corrosion resistance in wet and outdoor environments
• Compact form factor at 1.02 pounds for easy handling and installation
• Single-piece adapter simplifies FNST-to-MIPT transitions without additional fittings

Compatibility

Designed as an OEM-style replacement or new-installation fitting for fire protection and water supply systems requiring a 2.5-inch FNST to 2-inch MIPT adapter connection.

Installation Notes

Installation should be performed by a licensed plumber or certified fire protection contractor in accordance with applicable local codes and NFPA standards. Shut off the water supply and depressurize the line before threading the adapter onto any existing piping. Apply thread sealant tape or compound rated for potable and fire protection water service to the MIPT threads before assembly. Do not over-tighten; use appropriate pipe wrenches and inspect for leaks before returning the system to service.
