Merit Brass XNL112-3216 Pipe Reducer Coupling 2x1 Inch Fnpt

Product Description

The MERIT BRASS XNL112-3216 is a brass pipe reducer coupling designed to connect two pipes of different diameters in a threaded piping system. It accepts female National Pipe Taper (FNPT) threads on both ends and transitions from a 2-inch nominal pipe size down to a 1-inch nominal pipe size. Rated at 125 lb pressure class, this fitting is manufactured from brass with a rough finish. Licensed plumbers and pipe fitters install this type of reducer coupling in water supply, low-pressure steam, and general fluid service lines where a concentric pipe size reduction is required in a single fitting.

This reducer coupling is suited for residential and light commercial plumbing and piping applications. It is used in situations where a branch line or downstream segment requires a smaller pipe diameter than the supply line feeding it. The FNPT thread configuration on both ends allows for straightforward assembly using standard pipe thread sealant or PTFE tape. Typical install locations include mechanical rooms, boiler rooms, and utility piping runs where brass fittings are preferred for corrosion resistance in water or low-pressure steam service.

Key Features

• Reduces from 2-inch nominal to 1-inch nominal pipe size in a single fitting
• FNPT threads on both ends for standard threaded pipe assembly
• 125 lb pressure class rating suitable for water and low-pressure steam service
• Brass construction provides corrosion resistance in water and fluid systems
• Rough finish as manufactured, compatible with standard pipe dope or PTFE tape sealing

Compatibility

Designed as an OEM-style threaded brass reducer coupling for use with standard NPT-threaded pipe and fittings rated at 125 lb pressure class in residential and commercial piping systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve system pressure before disassembling any existing piping. Apply pipe thread sealant or PTFE tape to the male threaded pipe ends before assembly. Hand-tighten first, then use a pipe wrench to bring the joint to full thread engagement without over-stressing the fitting.
