Midland Industries 63549 Reducer Hex Bushing 3x1.25in Ss

Product Description

The MIDLAND INDUSTRIES 63549 is a reducer hex bushing designed to step down pipe connections from a 3-inch male pipe thread (MPT) to a 1-1/4-inch female pipe thread (FPT). Constructed from 316 stainless steel, this fitting delivers strong corrosion resistance in demanding environments including chemical, marine, and industrial fluid systems. It is rated for a pressure class of 150 lb at 300 psi and conforms to ASME B1.20.1 thread dimension standards. The hex body allows for standard wrench installation, making it a practical choice for plumbers, pipefitters, and industrial maintenance technicians working with threaded piping systems.

This bushing is suited for residential, commercial, and light industrial applications where a threaded pipe size reduction is required in a stainless steel system. Its 3-8 thread designation and 150 lb pressure class make it appropriate for water, steam, chemical, and process piping lines that demand corrosion-resistant fittings. It fits into standard NPT-threaded piping layouts and is commonly used when transitioning between larger and smaller pipe runs within a manifold, header, or distribution assembly.

Key Features

• 316 stainless steel construction provides superior corrosion resistance compared to 304 SS or iron fittings
• 3-inch MPT inlet to 1-1/4-inch FPT outlet allows direct in-line pipe size reduction
• 150 lb pressure class rated to 300 psi for reliable performance in pressurized systems
• Hex body design accommodates standard pipe wrenches or hex wrench tooling for secure installation
• Thread dimensions conform to ASME B1.20.1 for consistent fit with standard NPT fittings

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 150 lb rated NPT threaded piping systems requiring a 3-inch to 1-1/4-inch threaded reduction in 316 stainless steel.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or ASME piping codes. Shut off and depressurize the line completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten, as this can crack or distort the fitting body or damage mating threads.
