Merit Brass SW3611HD-16 Half Coupling 1 in 316 Ss 3000 Psi

Product Description

The MERIT BRASS SW3611HD-16 is a 1-inch pipe half coupling designed for socket weld connections in high-pressure piping systems. Machined from 316 stainless steel, it provides strong corrosion resistance in aggressive environments including chemical process, marine, and industrial service lines. The half coupling is rated to 3,000 psi, making it suitable for demanding pressure applications. It connects one socket weld end to a branch outlet or pipe stub, allowing a lateral connection to be made on a run pipe. Plumbers, pipefitters, and industrial maintenance technicians install this fitting in both new construction and retrofit applications.

This half coupling is used in residential and commercial piping systems where high-pressure socket weld connections are required. It is well suited for process piping, steam lines, hydraulic systems, and other applications that demand the corrosion resistance of 316 stainless steel. The socket weld by socket weld configuration allows the fitting to be welded directly to pipe on both ends, creating a leak-tight joint without threaded connections. It is commonly found in industrial plants, marine installations, and chemical processing facilities.

Key Features

• 316 stainless steel construction provides superior corrosion resistance in harsh and chemical-laden environments
• 3,000 psi pressure rating supports high-pressure piping applications
• Socket weld by socket weld end connection for strong, permanent welded joints
• 1-inch fitting size for standard pipe compatibility
• Half coupling design allows branch or stub-out connections on existing pipe runs

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-inch socket weld piping systems requiring 316 stainless steel construction and a 3,000 psi pressure rating.

Installation Notes

Installation should be performed by a qualified pipefitter or welder following applicable codes such as ASME B31.1 or B31.3 for pressure piping. De-pressurize and drain the line completely before cutting into an existing system. The socket weld joint requires proper fit-up and a certified weld procedure to achieve the rated pressure. Do not over-insert the pipe stub into the socket; maintain the required gap per applicable welding standards before welding.
