Midland Industries 63776MS Half Coupling 1-1/4 in 316 Ss

Product Description

The MIDLAND INDUSTRIES 63776MS is a half coupling fitting designed for pipe connections requiring both Female NPT and Socket Weld end configurations in a single compact body. Machined from 316 stainless steel, this fitting delivers strong corrosion resistance in demanding fluid and gas piping systems. It carries a 150 lb pressure class rating and features a 1-1/4-11-1/2 thread form on the NPT end. The half coupling is used where a full coupling is not required, typically when connecting a pipe branch to a vessel, tank, or header wall. Plumbers, pipefitters, and mechanical contractors install this type of fitting in both industrial and commercial piping assemblies.

This fitting is suited for use in 1-1/4 inch piping systems where a transition between a threaded Female NPT connection and a socket weld connection is needed. The 316 stainless steel construction makes it appropriate for corrosive service environments including chemical processing, marine, food-grade, and high-moisture mechanical systems. It fits within the SP-114 fittings product family and is commonly used in commercial plumbing, industrial process piping, and mechanical system fabrication where stainless steel fittings are specified.

Key Features

• 316 stainless steel construction for superior corrosion resistance in harsh or wet environments
• Dual connection type: 1-1/4 in Female NPT on one end, 1-1/4 in Socket Weld on the other
• 150 lb pressure class rating suitable for standard industrial and commercial piping service
• 1-1/4-11-1/2 thread specification on the NPT end for reliable thread engagement
• Compact half coupling form factor for branch connections to headers, tanks, or vessels

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/4 inch stainless steel piping systems requiring a Female NPT to Socket Weld half coupling within a 150 lb pressure class application.

Installation Notes

Installation should be performed by a licensed pipefitter or plumber in accordance with applicable mechanical and plumbing codes. Depressurize and drain the piping system fully before cutting into any existing line or removing a fitting. The socket weld end requires proper fit-up and gap spacing before welding per applicable welding procedures. Apply appropriate thread sealant to the NPT end and torque to the fitting manufacturer's standard for stainless steel NPT connections.
