Merit Brass SWM611H-12 Half Coupling 3/4 in 316 Ss

Product Description

The MERIT BRASS SWM611H-12 is a 3/4-inch pipe half coupling designed for socket weld connections in industrial and commercial piping systems. Manufactured from 316 stainless steel, this fitting offers strong resistance to corrosion and oxidation, making it well suited for demanding service environments. The threaded end connection allows for straightforward integration into existing threaded pipe assemblies, while the socket weld end provides a secure, permanent joint when fillet-welded in place. Rated at 150 psi, this half coupling is appropriate for moderate-pressure piping applications. Plumbers, pipefitters, and mechanical contractors working on stainless steel pipe systems will find this fitting suitable for a range of installation scenarios.

This half coupling is used in residential and commercial plumbing, process piping, and mechanical systems where a branch connection or end termination is needed on a 3/4-inch pipe run. The 316 stainless steel construction makes it a practical choice for applications involving mild chemicals, moisture-heavy environments, or corrosive media. It is sold individually and is compatible with standard 3/4-inch pipe fittings in socket weld configurations.

Key Features

• 316 stainless steel construction provides corrosion resistance in demanding service environments
• Socket weld by socket weld end connection for secure, permanent piping joints
• Threaded connection type for easy integration into threaded pipe assemblies
• 150 psi pressure rating suitable for moderate-pressure systems
• 3/4-inch fitting size for standard pipe configurations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 3/4-inch socket weld pipe systems in industrial and commercial plumbing applications.

Installation Notes

Installation should be performed by a licensed pipefitter or plumber in accordance with applicable codes such as the IPC or ASME B31.3 for process piping. Shut off and depressurize the line completely before cutting or modifying any existing piping. Socket weld connections require proper fit-up and fillet welding by a qualified welder. Inspect all joints for leaks before returning the system to service.
