Value Collection 455-043NL Brass Pipe Bushing 3/4x1/2 Mpt

Product Description

The VALUE COLLECTION 455-043NL is a red brass pipe bushing designed to reduce a 3/4-inch male pipe thread (MPT) connection down to a 1/2-inch MPT connection in pressurized piping systems. Rated at 125 psi and classified as Class 125, this bushing is suited for low-to-medium pressure plumbing, HVAC condensate, and general fluid-handling applications. The red brass construction provides corrosion resistance in both potable water and light industrial service lines. Plumbers and pipefitters install this fitting during rough-in or retrofit work where pipe diameter transitions are needed at threaded connections.

This bushing is used in residential and light commercial plumbing systems wherever a 3/4-inch threaded port must be reduced to accept 1/2-inch threaded pipe or fittings. Typical applications include water supply lines, boiler piping, HVAC condensate drainage manifolds, and compressed-air distribution systems operating within the 125 psi Class 125 pressure rating. It is also used in irrigation and pool equipment plumbing where brass fittings are preferred over plastic for durability and heat tolerance.

Key Features

• Red brass construction resists corrosion in water and light fluid service
• Class 125 pressure rating at 125 psi for low-to-medium pressure systems
• Male pipe thread (MPT) on both ends for standard threaded pipe connections
• Compact hex bushing profile fits standard pipe wrenches and adjustable wrenches
• 3/4-inch to 1/2-inch reduction covers one of the most common pipe transition sizes in trade plumbing

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with standard NPT threaded pipe systems rated at Class 125 or lower pressure service.

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 before installing or removing any threaded fitting. Apply thread sealant tape or pipe dope to the male threads before assembly and tighten with a pipe wrench to appropriate engagement — do not overtighten brass fittings, as the material is softer than iron and threads can strip. Inspect for leaks after restoring system pressure.
