Midland Industries 44543 Bronze Hex Bushing 4x3 in Mpt Fpt

Product Description

The MIDLAND INDUSTRIES 44543 is a bronze hex bushing designed to reduce a 4-inch male pipe thread (MPT) connection to a 3-inch female pipe thread (FPT) connection. Built to handle working pressures up to 125 psi, this fitting is manufactured from solid bronze for corrosion resistance in water, gas, and fluid piping systems. It conforms to ANSI B16.15 dimensional standards, ensuring consistent fitment and thread engagement. The hex body allows for standard wrench installation. Plumbers and pipefitters install this type of reducer bushing when transitioning between pipe sizes within a threaded assembly.

This bushing is suited for residential and commercial plumbing systems where a threaded pipe size reduction is required within a bronze fitting assembly. Typical applications include water supply lines, low-pressure gas distribution systems, and industrial fluid piping where bronze construction is specified for compatibility with the conveyed medium. The 4-inch MPT inlet and 3-inch FPT outlet make it appropriate for larger-diameter piping runs that step down to a smaller branch or equipment connection.

Key Features

• Bronze construction provides corrosion resistance for water, gas, and fluid service
• 4-inch MPT x 3-inch FPT configuration for one-step pipe size reduction
• Rated to 125 psi working pressure
• Hex body profile accepts standard pipe wrenches or hex wrenches for secure installation
• Conforms to ANSI B16.15 dimensional standards

Compatibility

Designed as an OEM-style bronze threaded fitting for use in standard NPT threaded piping assemblies conforming to ANSI B16.15 specifications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and ANSI standards. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not over-torque the fitting, as bronze fittings can crack under excessive force.
