Merit Brass SWM611-12 3/4 in 316 Ss Socket Weld Coupling

Product Description

The MERIT BRASS SWM611-12 is a 3/4-inch pipe coupling manufactured from 316 stainless steel. It connects two pipe sections using a socket weld by socket weld end configuration with threaded engagement, rated to 150 psi. The 316 stainless steel construction provides corrosion resistance in demanding environments, including wet, chemical, and marine-adjacent applications. This coupling is a standard component used in piping systems by licensed plumbers, pipefitters, and mechanical contractors working on process, industrial, or commercial installations. It weighs 0.32 pounds, making it easy to handle during installation.

This coupling is suited for 3/4-inch pipe assemblies in both commercial and light industrial piping systems where corrosion resistance and pressure integrity are required. Typical applications include process fluid lines, compressed air systems, and water service lines where 316 stainless steel material compatibility is specified. Socket weld fittings are common in higher-integrity piping assemblies where leak-free joints are critical. Each unit is sold individually.

Key Features

• 316 stainless steel construction for strong corrosion resistance in wet and chemical environments
• Socket weld by socket weld end connection for secure, leak-resistant joints
• 150 psi pressure rating suitable for standard commercial and light industrial service
• 3/4-inch fitting size for direct compatibility with standard 3/4-inch pipe
• Threaded connection type for straightforward assembly with standard pipe threads
• Compact and lightweight at 0.32 pounds for easy handling during installation

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/4-inch socket weld pipe assemblies requiring 316 stainless steel material and a 150 psi pressure rating.

Installation Notes

Installation of socket weld fittings is typically performed by licensed pipefitters or plumbers in accordance with applicable mechanical and plumbing codes, including ASME B31.3 for process piping where relevant. Shut off and depressurize the piping system fully before removing any existing fittings or making new connections. Proper weld preparation and filler metal selection compatible with 316 stainless steel are required to maintain joint integrity and corrosion resistance. Do not overtighten threaded connections, as this may damage threads or compromise the seal.
