Midland Industries 63537 Reducer Hex Bushing 3x1.5 in Ss

Product Description

The MIDLAND INDUSTRIES 63537 is a reducer hex bushing designed to step down pipe connections from a 3-inch male pipe thread (MPT) to a 1-1/2-inch female pipe thread (FPT). Constructed from 316 stainless steel, this fitting delivers strong corrosion resistance in demanding environments including chemical, marine, and high-moisture applications. It carries a 150 lb pressure class rating with a maximum working pressure of 300 psi. The hex head allows for wrench engagement during installation, making it a straightforward choice for plumbers and pipefitters handling threaded galvanized or stainless pipe systems.

This fitting suits residential and commercial plumbing, industrial process piping, and fluid handling systems where a reduction in pipe size is required between a 3-inch and 1-1/2-inch threaded connection. The 316 stainless steel construction makes it appropriate for corrosive media, outdoor installations, and environments where 304 SS or carbon steel would not hold up. It is a standard 150 lb class fitting and fits within typical low-pressure compressed air, water, and compatible liquid service lines.

Key Features

• 316 stainless steel construction for superior corrosion resistance in harsh environments
• 3-inch MPT x 1-1/2-inch FPT reducer configuration for in-line pipe size reduction
• 150 lb pressure class rated to 300 psi working pressure
• Hex head design enables standard wrench engagement for secure installation
• Conforms to ASME B1.20.1 thread dimension standards
• 3-8 thread designation for proper thread engagement and leak-free sealing

Compatibility

Designed as an OEM-style replacement or direct-fit component for 150 lb class threaded pipe systems using 3-inch MPT inlet and 1-1/2-inch FPT outlet connections in 316 stainless steel service.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC code requirements for the service type. Depressurize and drain the line fully before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before engagement. Do not over-torque; thread engagement should be firm and leak-free without stressing the fitting body.
