Merit Brass XB114-1612 Brass Pipe Bushing 1x3/4 in Class 125

Product Description

The MERIT BRASS XB114-1612 is a threaded brass pipe bushing designed to reduce a 1-inch female pipe thread to a 3/4-inch female pipe thread connection. It features male BSP tapered (MBSPT) inlet threads on the outer diameter and female BSP tapered (FBSPT) threads on the inner bore, allowing inline pipe size reduction in pressurized systems. Rated Class 125, this bushing is suited for low-to-medium pressure plumbing, HVAC hydronic piping, and general industrial piping applications. Licensed plumbers and pipefitters install this fitting as a standard reducing connection in new construction and retrofit work.

This bushing is appropriate for residential and light commercial plumbing and hydronic systems where a threaded pipe size reduction from 1 inch down to 3/4 inch is needed. It is commonly installed in water supply lines, boiler piping, and gas-rated threaded assemblies where Class 125 brass fittings meet code requirements. The all-brass construction resists corrosion in water and moderate chemical service environments, making it a reliable choice in wet mechanical rooms and utility spaces.

Key Features

• Reduces 1-inch pipe connection to 3/4-inch in a single fitting
• MBSPT x FBSPT threaded ends for standard tapered pipe thread engagement
• Class 125 pressure rating for low-to-medium pressure service
• Brass construction provides corrosion resistance in water and hydronic applications
• Compact hex-body bushing profile installs with standard pipe wrenches

Compatibility

Designed as an OEM-style replacement or new-installation fitting for threaded pipe systems requiring a 1 x 3/4-inch reducing bushing with Class 125 brass construction.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with the applicable International Plumbing Code (IPC) or local authority having jurisdiction. Shut off and depressurize the pipe system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly and tighten with a pipe wrench to full thread engagement. Do not over-torque brass fittings, as this can crack the hex body or distort the seat.
