Value Collection 454-054NL Reducing Coupling 1x3/4 Mpt

Product Description

The VALUE COLLECTION 454-054NL is a brass pipe reducing coupling designed to connect male-threaded pipe sections of two different diameters in a single inline fitting. Rated at 125 psi and manufactured in red brass, this Class 125 coupling accepts 1-inch male pipe thread on one end and 3/4-inch male pipe thread on the other, allowing a controlled diameter reduction without additional adapters. At 0.37 pounds and compact in profile, it is suited for tight plumbing runs. Licensed plumbers and pipefitters install this type of fitting in both potable water and general fluid-handling systems where pressure does not exceed 125 psi.

This reducing coupling sees use in residential and light commercial plumbing applications where supply lines transition between pipe sizes. Typical install scenarios include water distribution headers, boiler supply piping, irrigation manifolds, and general pipe-to-pipe connections requiring a step-down from 1-inch to 3/4-inch pipe. The red brass construction resists corrosion in wet service environments and is compatible with copper alloy and brass-rated thread sealants and tape.

Key Features

• Red brass construction for corrosion resistance in wet and potable water service
• 125 psi pressure rating for standard residential and light commercial systems
• MPT connections on both ends allow direct thread engagement without additional fittings
• Reduces pipe diameter from 1 inch to 3/4 inch in a single fitting
• Class 125 rated for consistent performance at rated pressure
• Compact form factor at 2.75 inches height and 1.75 inches width

Compatibility

Designed as a standard Class 125 MPT reducing coupling for 1-inch to 3/4-inch male-threaded brass and compatible pipe systems in general plumbing and fluid-handling applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off and depressurize the supply line fully before threading or unthreading any fittings. Apply a rated thread sealant tape or pipe dope to male threads before engagement to ensure a leak-free joint. Do not over-torque threaded brass fittings, as brass threads can crack under excessive force.
