Midland Industries 64435 Reducing Coupling 1/2 Fpt X 3/8 Fpt

Product Description

The MIDLAND INDUSTRIES 64435 is a galvanized malleable iron reducing coupling designed to connect two female-threaded pipe ends of different sizes in low-pressure piping systems. It steps down from a 1/2-inch FPT connection to a 3/8-inch FPT connection, using 1/2-14 and 3/8-18 NPT thread forms. Built to a 150 lb pressure class and conforming to ANSI B16.3 dimensional standards, this fitting is rated for service across a temperature range of -20 to 350 degrees F. Plumbers and pipefitters install it in residential and light commercial systems where a threaded size reduction is needed at a junction point.

This reducing coupling is suited for use in water supply, gas distribution, and general-purpose piping applications where galvanized malleable iron fittings are specified. The 150 lb pressure class rating makes it appropriate for standard residential and light commercial service lines. It is commonly installed in threaded pipe assemblies during new construction, retrofit work, or repair where a reduction from 1/2-inch to 3/8-inch female thread is required at a fitting connection.

Key Features

• Steps down from 1/2 in FPT to 3/8 in FPT in a single compact fitting
• Malleable iron construction with galvanized finish for corrosion resistance
• Rated to 150 lb pressure class per ANSI B16.3
• Temperature rated from -20 to 350 degrees F
• 1/2-14 x 3/8-18 NPT thread form for standard pipe compatibility
• Compact body at approximately 1.25 inches in length

Compatibility

Designed as an OEM-style replacement or new-installation fitting for threaded malleable iron pipe systems using 1/2-inch and 3/8-inch female NPT connections rated at 150 lb pressure class.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable IPC and IFGC code requirements for the system type. Shut off and depressurize the line fully before disassembling any fittings. Apply appropriate thread sealant or PTFE tape to all male threads before assembly. Do not over-tighten threaded connections in malleable iron fittings, as excessive torque can crack the fitting body.
