Merit Brass SW3411D-06 3/8 in Ss Pipe Coupling 3000 Psi

Product Description

The MERIT BRASS SW3411D-06 is a 3/8-inch socket weld pipe coupling manufactured from 304 stainless steel. It connects two pipe sections using a socket weld end connection on each side and features threaded construction rated for pressures up to 3,000 psi. This coupling is built to Class 3000 standards, making it appropriate for high-pressure piping systems in industrial, mechanical, and commercial applications. Licensed plumbers and pipefitters install this fitting as part of pressurized fluid or gas line assemblies where corrosion resistance and pressure integrity are required.

This coupling is suited for use in high-pressure piping systems that require a reliable socket weld connection at the 3/8-inch pipe size. Its 304 stainless steel construction provides resistance to corrosion in wet, chemical, or marine environments. Typical installation scenarios include process piping, mechanical rooms, and commercial plumbing systems where stainless fittings are specified by code or design. It is sold and packaged as an individual unit.

Key Features

• 304 stainless steel construction for corrosion resistance in demanding environments
• 3,000 psi pressure rating suitable for high-pressure piping applications
• Socket weld x socket weld end connections for secure, leak-resistant pipe joining
• 3/8-inch fitting size for standard small-bore piping systems
• Threaded design for compatibility with standard coupling assembly methods

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/8-inch socket weld piping systems rated to Class 3000 pressure specifications.

Installation Notes

This fitting is installed by licensed plumbers or pipefitters in accordance with applicable codes such as ASME B16.11 for socket weld fittings. Depressurize and drain the piping system fully before removing or installing any fitting. Socket weld connections require proper fit-up and fillet welding by a qualified welder — do not substitute mechanical attachment for the specified weld joint. Follow all applicable local and national piping codes for pressure system work.
