Matco-norca mn-ft3rc0403 Threaded Reducing Coupling

Product Description

The MATCO-NORCA mn-ft3rc0403 is a forged steel threaded reducing coupling designed to connect pipes of two different diameters in pressurized piping systems. It transitions from a 3/4-inch threaded connection on one end to a 1/2-inch threaded connection on the other. Manufactured from ASTM A105N forged steel, this coupling delivers the structural integrity and pressure resistance required in demanding plumbing, mechanical, and industrial piping applications. Licensed plumbers and pipefitters install this fitting during new construction and retrofit work where pipe size reduction is needed without an additional union or nipple.

This reducing coupling is suited for residential and commercial plumbing systems, gas distribution lines, and mechanical piping where a threaded connection is the specified joining method. The forged construction makes it appropriate for higher-pressure service conditions compared to cast fittings. It is a standard choice for in-line pipe reduction on steel pipe runs where both ends require NPT-style threaded engagement.

Key Features

• Reduces from 3/4-inch to 1/2-inch in a single inline fitting
• Both ends are threaded for standard NPT pipe engagement
• Forged from ASTM A105N steel for high-pressure service suitability
• Forged manufacturing method produces a dense, uniform grain structure
• Compatible with standard steel pipe threaded installations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for threaded steel pipe systems requiring a 3/4-inch to 1/2-inch inline reduction.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing and mechanical codes, including IPC and IFGC requirements where relevant. Shut off and depressurize the line before cutting into any existing piping. Apply an appropriate thread sealant or PTFE tape to all male threads before engagement. Do not over-torque the fitting, as forged steel threads can be damaged by excessive force applied without a backup wrench.
