Merit Brass SW3411HD-16 Half Coupling 1 in Ss 3000 Psi

Product Description

The MERIT BRASS SW3411HD-16 is a 1-inch pipe half coupling designed for socket weld installations in high-pressure piping systems. Constructed from 304 stainless steel, this half coupling provides a single socket weld end connection, allowing a pipe to be joined to a vessel, valve, or other fitting without a through-bore. Rated at 3,000 psi, it is suited for demanding industrial and mechanical piping applications. Licensed plumbers, pipefitters, and industrial maintenance technicians install this type of fitting where corrosion resistance and pressure integrity are required.

This half coupling is used in socket weld piping configurations found in commercial and industrial facilities, including process piping, hydraulic lines, and utility systems. Its 304 stainless steel construction makes it appropriate for systems handling water, steam, mild chemicals, and other media where corrosion resistance is a priority. It is sold individually and fits standard 1-inch pipe schedules compatible with socket weld Class 3000 fittings.

Key Features

• 3,000 psi pressure rating suitable for high-pressure piping service
• 304 stainless steel construction for corrosion resistance
• Socket weld end connection for secure, leak-resistant joints
• 1-inch fitting size for standard pipe connections
• Half coupling design for connecting pipe to flat or threaded surfaces

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Class 3000 socket weld piping systems using 1-inch pipe.

Installation Notes

Installation of socket weld fittings should be performed by a qualified pipefitter or licensed plumber in accordance with applicable codes such as ASME B16.11 and facility-specific piping specifications. Before installation, depressurize and isolate the piping system completely. Socket weld joints require proper gap spacing between the pipe end and fitting socket shoulder before welding to prevent weld cracking. Post-weld inspection may be required per project or code specifications.
