Merit Brass XNL112-1612 Pipe Reducer Coupling 1x3/4 in Fnpt

Product Description

The MERIT BRASS XNL112-1612 is a threaded pipe reducer coupling designed to connect two pipes of different diameters in a plumbing or piping system. It transitions from a 1-inch nominal inlet to a 3/4-inch nominal outlet using Female National Pipe Taper (FNPT) threads on both ends. Rated at 125 lb, this coupling is constructed from rough brass, providing solid corrosion resistance in standard water supply, low-pressure gas, and general fluid-handling applications. Licensed plumbers and pipefitters install this fitting during new construction and retrofit work where pipe diameter reduction is required in a threaded piping assembly.

This reducer coupling is suited for residential and light commercial plumbing systems, hydronic heating distribution lines, and general industrial piping where a threaded brass fitting is specified. The FNPT connection style makes it compatible with standard NPT-threaded male pipe ends. The 1-inch to 3/4-inch size reduction is a common transition in domestic water supply lines, irrigation manifolds, and compressed-air distribution systems.

Key Features

• Transitions 1-inch nominal pipe to 3/4-inch nominal pipe in a single fitting
• FNPT threads on both ends for connection to standard NPT male pipe ends
• 125 lb pressure class brass construction for corrosion-resistant service
• Rough brass finish suitable for burial, concealed, or functional exposed installations
• Compact reducer coupling profile minimizes installation space requirements

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-inch to 3/4-inch nominal NPT-threaded piping systems in plumbing, hydronic, and general fluid-handling applications.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter. Shut off and depressurize the supply line before disassembling existing fittings or installing new ones. Apply thread sealant tape or pipe-joint compound to the male NPT threads before making up the connection; do not apply sealant to female threads. Follow applicable plumbing codes, including IPC requirements, for fitting selection, support spacing, and pressure testing after installation.
