Midland Industries 63436 Reducing Coupling 3/4x1/4 Fpt Ss

Product Description

The MIDLAND INDUSTRIES 63436 is a 150 lb rated reducing coupling designed to connect two female pipe thread (FPT) ports of different sizes within a piping system. The larger end accepts a 3/4 in FPT connection and the smaller end accepts a 1/4 in FPT connection, with thread specifications of 3/4-14 and 1/4-18 respectively. Constructed from 316 stainless steel, this coupling offers strong resistance to corrosion in demanding service environments. It weighs 0.205 pounds and measures approximately 1.75 inches in length, 1.4 inches in height, and 1.35 inches in width. Licensed plumbers and pipefitters install this fitting in compressed air, water, oil, natural gas, and steam service lines.

This reducing coupling is suited for residential and commercial piping applications where a size transition between 3/4 in and 1/4 in female-threaded ports is required. Its 316 stainless steel construction makes it appropriate for use in corrosive environments, marine-adjacent installations, and systems carrying natural gas or steam where material integrity is critical. The 150 lb pressure class fits standard low-to-moderate pressure piping systems across multiple fluid and gas media.

Key Features

• 316 stainless steel construction for superior corrosion resistance
• 150 lb pressure class rating suitable for standard service conditions
• 3/4 in FPT x 1/4 in FPT configuration for direct size reduction in threaded piping
• Compatible with air, water, oil, natural gas, and steam service
• Compact profile at 1.75 inches in length for tight installation spaces
• Thread specifications 3/4-14 x 1/4-18 for precise thread engagement

Compatibility

Designed as an OEM-style threaded reducing coupling for use in 150 lb rated piping systems carrying air, water, oil, natural gas, or steam where a 3/4 in to 1/4 in FPT size reduction is required.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Shut off and depressurize the system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to all male threads before assembly; do not apply sealant to female threads. Follow applicable plumbing and mechanical codes, including IPC and IFGC requirements, for material selection and pressure ratings in the specific service application.
