Merit Brass C114-1608 Brass Pipe Bushing 1x1/2 Mnpt Fnpt

Product Description

The MERIT BRASS C114-1608 is a brass pipe bushing designed to reduce a 1-inch male NPT connection down to a 1/2-inch female NPT port. It serves as a threaded reducer in pressurized piping systems, allowing techs to connect a smaller-diameter line to a larger-diameter fitting or valve body without additional adapters. Built to Class 125 pressure standards, this bushing is suited for plumbing, HVAC hydronic lines, and general-purpose piping applications. Brass construction resists corrosion and handles moderate working pressures across a wide range of service conditions. Plumbers, pipefitters, and HVAC mechanics are the primary installers.

This bushing fits standard NPT threaded pipe assemblies in residential and light commercial installations. Typical use cases include reducing threaded ports on valves, manifolds, boiler supply and return connections, and distribution headers where a 1-inch to 1/2-inch size transition is needed. The MNPT x FNPT end configuration allows it to thread directly into a female-threaded fitting body on one end and accept a male-threaded pipe or fitting on the other.

Key Features

• Reduces 1-inch MNPT to 1/2-inch FNPT in a single fitting
• Class 125 pressure rating suitable for standard service piping
• Brass construction provides corrosion resistance in water and hydronic systems
• Standard NPT threads for compatibility with common pipe and fitting stock
• Compact hex-body design allows wrench engagement for proper thread engagement torque

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 1-inch to 1/2-inch NPT threaded piping systems in plumbing and HVAC applications.

Installation Notes

Installation is performed by licensed plumbers or HVAC mechanics working on threaded pipe systems. Shut off the water supply or drain the system and relieve pressure before removing or installing any threaded fitting. Apply thread sealant tape or a compatible pipe dope to the male threads before assembly. Hand-tighten first, then use a pipe wrench or strap wrench to achieve proper engagement without over-torquing the brass fitting body.
