Midland Industries 63456MS Reducing Coupling 3in X 2in 316 Ss

Product Description

The MIDLAND INDUSTRIES 63456MS is a reducing coupling designed to connect two female NPT threaded pipe sections of different diameters in a single inline fitting. It steps down from a 3-inch female NPT on one end to a 2-inch female NPT on the other, making it a practical solution for reducing line size without additional adapters. Constructed from 316 stainless steel, the fitting offers strong resistance to corrosion and chemical exposure. Rated at 150 lb pressure class, it suits a wide range of industrial and commercial piping applications. Plumbers, pipefitters, and mechanical contractors are the primary installers of this fitting.

This reducing coupling is used in fluid handling, process piping, and utility systems where a line reduction from 3 inches to 2 inches is required. The 316 stainless steel construction makes it suitable for corrosive media, marine environments, chemical processing lines, and food-grade or sanitary-adjacent systems where iron fittings are not acceptable. It falls within the SP-114 fittings series and is rated for standard 150 lb service conditions.

Key Features

• Steps down from 3-inch female NPT to 2-inch female NPT in a single fitting

• 150 lb pressure class rating for standard industrial and commercial service
• Thread specification: 3-8 NPT on the large end, 2-11-1/2 NPT on the small end
• Compact body dimensions support installation in tight piping layouts

Compatibility

Designed for use in standard 150 lb class NPT threaded piping systems requiring a 3-inch to 2-inch inline diameter reduction. Part of the SP-114 316 stainless steel fittings series.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes. Depressurize and drain the line fully before removing or installing any threaded fitting. Apply an appropriate thread sealant rated for the media and pressure class before threading the fitting into place. Do not overtighten; use a pipe wrench sized for the fitting to avoid cracking the fitting body or distorting threads.
