Merit Brass SW3611HD-06 Pipe Half Coupling 316 Ss

Product Description

The MERIT BRASS SW3611HD-06 is a 3/8 inch pipe half coupling manufactured from 316 stainless steel for socket weld installation. A half coupling provides a single-end branch connection, allowing a pipe to be welded into a larger fitting, vessel, or header without a full coupling run. With a 3,000 psi pressure rating and 316 grade stainless construction, this fitting is suited for demanding fluid and process piping applications where corrosion resistance and pressure integrity are critical. Installation is typically performed by a licensed plumber, pipefitter, or pipe welder working to applicable codes.

This fitting is used in industrial, commercial, and mechanical piping systems handling water, steam, chemicals, or other media requiring stainless steel wetted surfaces. The socket weld end connection on both ends allows secure, fillet-welded joints in high-pressure lines. Typical install scenarios include process piping, instrumentation taps, and branch connections on headers in facilities maintenance, chemical processing, and marine or food-service environments where 316 stainless is specified for chloride or corrosion resistance.

Key Features

• 316 stainless steel construction provides strong resistance to corrosion, chlorides, and oxidation
• 3,000 psi pressure rating for high-pressure piping service
• Socket weld end connection on both ends for fillet-welded installation
• 3/8 inch fitting size for standard pipe branch connections
• Half coupling design for single-end branch or tap applications

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/8 inch socket weld piping systems requiring 316 stainless steel half coupling connections rated to 3,000 psi.

Installation Notes

Installation should be performed by a qualified pipefitter or welder in accordance with applicable piping codes such as ASME B16.11 and applicable facility or mechanical codes. Depressurize and drain the line completely before cutting in or modifying any branch connection. Socket weld fittings require proper socket depth engagement and a fillet weld per applicable weld procedure specifications. Do not apply thread sealants or pipe dope to socket weld connections.
