Midland Industries 44431LFUSA Reducing Coupling Bronze

Product Description

The MIDLAND INDUSTRIES 44431LFUSA is a lead-free bronze reducing coupling designed to connect two female NPT-threaded pipes or fittings of different sizes. It transitions from a 3/8-in Female NPT (3/8-18 thread) on one end to a 1/8-in Female NPT (1/8-27 thread) on the other, making it a standard solution for reducing pipe runs in water, gas, and fluid distribution systems. Rated at a 125 lb pressure class, this fitting is manufactured from lead-free bronze, meeting requirements for potable water applications. Plumbers and pipefitters install this type of reducing coupling when reconfiguring line sizes during new construction or retrofit work.

This coupling is suited for residential and light commercial plumbing, gas distribution, and instrumentation lines where an NPT thread reduction is needed between a 3/8-in and 1/8-in port. It is commonly installed at fixture supply connections, gauge ports, control valve inlets, and similar small-bore applications. Its lead-free bronze construction makes it appropriate for potable water service in jurisdictions that enforce lead-free material mandates.

• 3/8-18 x 1/8-27 thread form per ASME B1.20.1
• Rated at 125 lb pressure class
• Meets AWWA C800, ASME B16.15, ASME B1.20.1, WW-P-460C, and MSS-SP-106 standards
• USA-manufactured lead-free bronze fitting

Compatibility

Designed as an OEM-style replacement or new-installation fitting for small-bore female NPT plumbing and gas systems requiring a 3/8-in to 1/8-in thread reduction.

Installation Notes

This fitting is installed by licensed plumbers or pipefitters following local plumbing codes and IFGC or IPC guidelines as applicable. Shut off and depressurize the line before removing any existing fitting or making new connections. Apply an appropriate thread sealant or PTFE tape to the male NPT threads mating into this coupling. Do not over-torque bronze fittings, as the material is softer than ferrous pipe and susceptible to thread damage.
