Midland Industries 62435B1 Barstock Reducing Coupling 1/2x3/8 Fpt

Product Description

The MIDLAND INDUSTRIES 62435B1 is a barstock reducing coupling designed to connect two female pipe thread (FPT) fittings of different sizes in a single inline transition. It steps down from a 1/2-inch FPT port to a 3/8-inch FPT port, with thread specifications of 1/2-14 and 3/8-18. Machined from 304 stainless steel and rated to 1000 lb pressure class, this fitting is suited for demanding service environments where corrosion resistance and pressure integrity are both required. Plumbers, pipefitters, and mechanical contractors install this type of coupling when reducing pipe size within a run without additional fittings.

This reducing coupling is rated for use with air, water, oil, natural gas, and steam, making it a versatile choice across plumbing, HVAC, industrial, and light commercial piping systems. It is appropriate for both residential and commercial installations where a threaded inline reduction is needed and 304 stainless steel is specified for the service fluid or environment. The 1000 lb pressure class positions it well above standard 150 lb fittings, suitable for higher-pressure process and utility lines.

Key Features

• Steps down from 1/2 in FPT to 3/8 in FPT in a single inline body
• 304 stainless steel construction for corrosion resistance in wet, chemical, and gas service
• 1000 lb pressure class rating for high-pressure applications
• Thread specifications: 1/2-14 NPT x 3/8-18 NPT for standard pipe thread engagement
• Compatible with air, water, oil, natural gas, and steam service
• Barstock machined body provides consistent dimensional accuracy and wall integrity

Compatibility

Rated for use with air, water, oil, natural gas, and steam. Designed as a 1000 lb class threaded reducing coupling for use in standard NPT piping systems requiring a 1/2 in to 3/8 in female-to-female inline reduction.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC requirements. Depressurize and isolate the line completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape rated for the service fluid. Do not over-torque stainless steel fittings, as galling can occur; hand-tighten first and use a pipe wrench for final engagement.
