Midland Industries 63410B Od Machine Coupling 1/8 Fpt 150 Lb

Product Description

The MIDLAND INDUSTRIES 63410B is a 316 stainless steel outside-diameter machined coupling designed for joining 1/8-inch female pipe thread connections in moderate-pressure piping systems. Rated at 150 lb pressure class with a 1/8-27 thread specification, this compact coupling measures 0.56 inches in diameter and 0.76 inches in length. Its 316 stainless steel construction provides strong resistance to corrosion in demanding service environments. The fitting is installed by licensed plumbers, pipefitters, and HVAC technicians working on small-bore piping runs where a clean, tight threaded union is required.

This coupling is suited for use in residential and light commercial systems across a wide range of media. It is rated for use with air, water, oil, natural gas, and steam, making it a versatile fitting choice for mechanical rooms, equipment connections, and instrumentation lines. Its small form factor is particularly useful in tight spaces where standard full-size couplings would not fit.

Key Features

• Low unit weight of 0.050 pounds simplifies handling and installation

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 150 lb rated small-bore piping systems using 1/8 in female pipe thread connections across air, water, oil, natural gas, and steam applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC requirements for the service medium. Depressurize and isolate the piping system completely before removing or installing any threaded fitting. Apply thread sealant or PTFE tape appropriate for the service medium to all male threads before assembly. Do not over-torque; inspect threads for damage before installation to ensure a leak-free joint.
