Merit Brass XNL112-3224 Pipe Reducer Coupling Brass Fnpt

Product Description

The MERIT BRASS XNL112-3224 is a brass pipe reducer coupling designed to connect two pipes of different diameters in a threaded plumbing or fluid-handling system. It transitions from a 2-inch nominal female connection to a 1-1/2-inch nominal female connection using FNPT (female National Pipe Taper) threading on both ends. Rated at 125 lb, this fitting handles standard working pressures common in residential and light commercial plumbing lines. The rough brass finish is typical for fittings that will be hidden in walls, mechanical rooms, or utility spaces. Licensed plumbers and pipefitters are the primary installers.

This reducer coupling is suited for residential and light commercial plumbing systems where a pipe run changes from 2-inch to 1-1/2-inch nominal pipe size. Typical applications include supply lines, drain-adjacent pressure lines, and mechanical room distribution manifolds where brass fittings are specified for corrosion resistance and long service life. The FNPT threading on both ends makes it compatible with standard NPT-threaded male adapters, nipples, valves, and other fittings in the same size range.

Key Features

• Reduces 2-inch nominal to 1-1/2-inch nominal pipe size in a single fitting
• FNPT threading on both ends for standard NPT-compatible connections
• 125 lb pressure rating suitable for standard plumbing service
• Brass construction offers corrosion resistance in water and many fluid systems
• Rough finish suitable for concealed or utility installations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard NPT threaded pipe systems using 2-inch and 1-1/2-inch nominal pipe sizes.

Installation Notes

Installation is typically performed by a licensed plumber. Shut off and depressurize the supply line completely before removing any existing fitting or threading in this coupling. Apply an appropriate thread sealant or PTFE tape to the male NPT threads being joined, following local plumbing code requirements such as those referenced in the IPC. Do not overtighten brass fittings; hand-tight plus wrench turns appropriate for NPT threads is standard practice to avoid cracking the fitting body.
