Merit Brass XB112-1612 Brass Reducing Coupling 1x3/4 in

Product Description

The MERIT BRASS XB112-1612 is a brass pipe reducing coupling designed to connect two different pipe sizes in threaded piping systems. It features female BSP tapered (FBSPT) threads on both ends, allowing a 1-inch pipe to transition down to a 3/4-inch pipe in a single fitting. Rated Class 125, this coupling is built for moderate-pressure service in plumbing, HVAC hydronic, and general-purpose piping applications. The all-brass construction provides corrosion resistance suitable for water, oil, and many common fluids. At 0.45 pounds, it is a compact, lightweight fitting that installs quickly with standard pipe wrenches.

This reducing coupling is used in residential and light commercial piping systems where a diameter change is required inline. Typical applications include water supply lines, low-pressure steam or hydronic loops, compressed air distribution, and general fluid conveyance. It is suited for installations where both connecting pipes carry FBSPT threads, eliminating the need for adapters or unions at the transition point. Plumbers and pipefitters install this fitting during new construction, system modifications, or repair work.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Class 125 threaded brass piping systems using 1-inch and 3/4-inch pipe sizes with FBSPT connections.

Installation Notes

A licensed plumber or pipefitter should install this coupling in accordance with local plumbing codes and IPC guidelines. Shut off and depressurize the piping system fully before removing any existing fittings or making new connections. Apply thread sealant tape or pipe compound to the male pipe threads before engagement. Do not over-tighten; use a pipe wrench with steady, controlled torque to seat the threads without cracking the fitting.
