Merit Brass SWM611H-16 Half Coupling 1 in 316 Ss

Product Description

The MERIT BRASS SWM611H-16 is a 1-inch pipe half coupling manufactured from 316 stainless steel, designed for socket weld connections with threaded engagement. It carries a 150 psi pressure rating, making it suitable for moderate-pressure piping systems in corrosive or sanitary service environments. The half coupling provides a compact, single-end fitting solution used to branch or terminate a run of pipe without a full-length coupling body. Plumbers and pipefitters install this fitting in systems where corrosion resistance and weld integrity are required. At 0.27 pounds, the part is lightweight and easy to handle during assembly.

This half coupling is used in industrial, commercial, and mechanical piping systems where 316 stainless steel is specified for corrosion resistance against chlorides, acids, or high-purity process fluids. The socket weld end accepts pipe inserted into the socket bore before welding, while the threaded connection allows direct engagement with NPT-threaded pipe or fittings. Typical applications include chemical processing lines, food service piping, marine systems, and HVAC hydronic piping where stainless material is required by spec or code.

Key Features

• 316 stainless steel construction provides superior corrosion resistance compared to 304-grade alloys
• Socket weld by socket weld end connection with threaded engagement for versatile installation
• 150 psi pressure rating suitable for moderate-pressure service
• 1-inch fitting size fits standard Schedule 40 and Schedule 80 pipe
• Compact half coupling profile reduces weight and material in space-constrained installations
• Sold individually, no minimum multi-pack requirement

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-inch socket weld piping systems using 316 stainless steel components rated to 150 psi.

Installation Notes

Installation requires a certified welder for the socket weld connection; follow applicable ASME B31.1 or B31.3 piping code requirements for weld procedure and inspection. Isolate and depressurize the piping system completely before cutting into any existing line. The threaded connection should be made with an appropriate thread sealant rated for the service fluid and temperature. Pipe threading and socket fit should be verified before welding to ensure proper alignment and joint integrity.
