Value Collection 454-032NL Brass Reducing Coupling Mpt

Product Description

The VALUE COLLECTION 454-032NL is a brass pipe reducing coupling designed to connect two male-threaded pipe sections of different diameters in a single inline fitting. It transitions from a 1/2-inch MPT connection down to a 3/8-inch MPT connection, making it a practical solution for reducing pipe size within a pressurized system. Rated at 125 psi and constructed in Class 125, this coupling suits a wide range of plumbing and fluid-handling applications. The red brass finish provides solid corrosion resistance in wet service environments. Licensed plumbers and pipefitters are the primary installers for this type of fitting in residential and light commercial systems.

This reducing coupling is suited for residential and light commercial plumbing systems where a size reduction between threaded male connections is required inline. Typical applications include potable water supply lines, hydronic heating distribution piping, and general fluid-handling assemblies operating within the 125 psi pressure rating. The MPT end connections on both sides allow direct threading into female-threaded fittings, valves, or pipe sections without adapters.

Key Features

• Reduces from 1/2-inch to 3/8-inch male pipe thread (MPT) in a single inline fitting
• Class 125 pressure rating at 125 psi for standard plumbing service
• Red brass construction offers dependable corrosion resistance in wet environments
• MPT end connections on both sides for direct threaded assembly
• Compact profile at 1.75 x 1.75 x 2.75 inches for installation in tight spaces

Compatibility

Designed as an OEM-style replacement or new-install reducing coupling for Class 125 threaded brass plumbing systems with 1/2-inch to 3/8-inch MPT connections.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC requirements. Shut off and depressurize the supply line fully before removing any existing fitting or threading this coupling into place. Apply an approved thread sealant or PTFE tape to all male threads before assembly to ensure a leak-free connection. Do not overtighten, as brass threads can be damaged by excessive force.
