Midland Industries 44431 Bronze Reducing Coupling

Product Description

The MIDLAND INDUSTRIES 44431 is a bronze reducing coupling designed to connect two female pipe threads of different sizes in a single fitting. It transitions from a 3/8-inch FPT (3/8-18 thread) on one end to a 1/8-inch FPT (1/8-27 thread) on the other, making it a compact solution for reducing pipe diameter within a threaded assembly. Measuring 0.92 inches in length and weighing 0.1 pounds, the fitting meets multiple dimensional and performance standards including ASME B16.15, ASME B1.20.1, AWWA C800, WW-P-460C, and MSS-SP-106. Bronze construction provides corrosion resistance suitable for water, gas, and fluid system applications.

This reducing coupling is used in residential and light commercial plumbing, HVAC, and fluid distribution systems where a threaded line must step down from 3/8-inch to 1/8-inch pipe size. It is commonly installed at instrument taps, gauge ports, pilot line connections, and branch reductions within copper or bronze piping assemblies. Licensed plumbers and pipefitters are the typical installers in code-governed applications.

Key Features

• Reduces from 3/8 in FPT to 1/8 in FPT in a single compact fitting
• Bronze construction resists corrosion in water, gas, and fluid service
• Meets ASME B16.15, ASME B1.20.1, AWWA C800, WW-P-460C, and MSS-SP-106 standards
• 3/8-18 x 1/8-27 thread form for accurate NPT engagement
• Compact at 0.92 inches in length and 0.1 pounds

Compatibility

Designed as an OEM-style replacement or new-installation fitting for threaded bronze pipe systems requiring a 3/8 in FPT to 1/8 in FPT reduction.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC requirements. Shut off and depressurize the supply line fully before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads being engaged, not the female threads of this coupling. Do not overtighten; bring the fitting to hand-tight, then use a pipe wrench only to achieve a proper seal without stressing the bronze body.
