Matco-norca mn-fw3un03 Forged Steel Sw Union CL3000 1/2 in

Product Description

The MATCO-NORCA mn-fw3un03 is a forged steel socket weld union rated Class 3000, designed for high-pressure piping systems where a removable, leak-tight connection is required. Socket weld unions allow two pipe sections to be joined and later separated without cutting the line, making them a standard choice in industrial and commercial piping installations. At 1/2 inch, this fitting suits smaller-diameter runs while still meeting the pressure demands of Class 3000 service. Licensed plumbers and pipefitters install these fittings in steam, hydraulic, and process piping applications.

This union is suited for 1/2 inch socket weld piping assemblies in commercial and industrial settings, including process plants, mechanical rooms, and high-pressure utility lines. The Class 3000 pressure rating makes it appropriate for systems where standard threaded or lower-rated fittings are not adequate. It is not intended for PVC, CPVC, or low-pressure residential applications.

Key Features

• Class 3000 pressure rating for high-pressure piping service
• Socket weld end connection for strong, full-penetration welds
• Forged steel construction for durability and pressure integrity
• 1/2 inch pipe size fits standard half-inch socket weld schedules
• Union design allows disassembly and reassembly without cutting pipe

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/2 inch socket weld piping systems rated to Class 3000 service pressure.

Installation Notes

Installation should be performed by a licensed pipefitter or plumber in accordance with applicable codes such as ASME B16.11 and local mechanical codes. Depressurize and drain the system completely before disassembling or installing any union fitting. Socket weld connections require proper fit-up and certified welding procedures; do not overtighten the union nut or use it as a structural support point.
