Matco-norca mn-fw3cp07 Socket Weld Coupling 1-1/2 in

Product Description

The MATCO-NORCA mn-fw3cp07 is a forged steel socket weld coupling rated for Class 3000 service. It is designed to join two sections of pipe using socket weld connections, making it a common fitting in high-pressure piping systems where a leak-tight, permanent joint is required. At 1-1/2 inches, this coupling fits standard pipe sizing in industrial and commercial applications. Licensed plumbers and pipefitters install this type of fitting on steam, hydraulic, and process piping where threaded connections are not acceptable and a full-penetration weld joint is specified.

This coupling is suited for high-pressure commercial and industrial piping installations, including steam distribution, hydraulic lines, and other process systems that demand Class 3000 rated components. The socket weld design allows the pipe to seat inside the fitting bore before welding, providing a clean, consistent joint. It is a standard choice in mechanical rooms, boiler rooms, and industrial process environments where code-required pressure ratings govern fitting selection.

Key Features

• Class 3000 pressure rating for high-pressure piping service
• Socket weld end connections for full-penetration weld joints
• Forged steel construction for strength and durability under pressure and temperature
• 1-1/2 inch size fits standard pipe dimensions
• Ships in quantities of 25 units per package, suited for project stocking

Compatibility

Designed as an OEM-style replacement or new-install fitting for Class 3000 forged steel socket weld piping systems using 1-1/2 inch pipe.

Installation Notes

Installation of socket weld fittings must be performed by a qualified pipefitter or licensed plumber in accordance with applicable mechanical and piping codes. The system must be fully depressurized, drained, and isolated before any fitting work begins. Socket weld connections require a qualified welder following applicable ASME or local welding procedure specifications. Do not apply heat to fittings while the line is pressurized or contains flammable media.
