Matco-norca b-bu0403 Hex Brass Reducing Bushing 3/4x1/2

Product Description

The MATCO-NORCA b-bu0403 is a hex brass reducing bushing designed to transition pipe connections from a 3/4-inch female thread down to a 1/2-inch female thread. Machined from brass meeting ASTM B62 and ASTM B584-93B material specifications, this fitting delivers reliable sealing performance in threaded piping assemblies. The hex body allows standard wrench engagement for controlled makeup torque. Rated at Class 125 pressure, it suits a wide range of plumbing and fluid-handling applications. Licensed plumbers and pipefitters install this type of fitting in both new construction and retrofit work.

This bushing is rated for residential, commercial, and industrial plumbing systems. Its dual female-thread end connections make it appropriate for joining male-threaded pipe, valves, and fittings where a reduction from 3/4 inch to 1/2 inch is required. The brass construction resists corrosion in potable water and general fluid service lines. The fitting conforms to ANSI/ASME B1.20.1 and B16.5 thread standards, ensuring dimensional interchangeability with standard NPT components across a broad range of system configurations.

Key Features

• Hex body profile provides secure wrench grip during installation and removal
• Female-threaded x female-threaded end connections for male pipe or fitting makeup
• Brass construction per ASTM B62 and ASTM B584-93B for corrosion resistance
• Class 125 pressure rating suitable for typical residential and commercial plumbing systems
• NSF 372 compliant for low lead content in potable water service
• Meets ANSI/ASME B1.20.1/B16.5 dimensional and thread standards

Compatibility

Designed as an OEM-style reducing bushing for threaded piping systems requiring a 3/4-inch to 1/2-inch female NPT transition in residential, commercial, and industrial plumbing applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the applicable local plumbing code and IPC guidelines. Shut off the water supply and relieve system pressure completely before working on any threaded connection. Apply thread sealant tape or compound to male threads per the fitting manufacturer and code requirements. Do not overtighten; use the hex body with a proper wrench and avoid pipe-wrench contact on the fitting body that could cause deformation.
