Fibre-metal 69029109177 Sw Coupling 1/4 in 3000lb A105

Product Description

The FIBRE-METAL 69029109177 is a forged steel socket weld coupling rated for 3000-pound pressure class service. Built to ASTM A105 carbon steel material standards, this fitting accepts pipe into recessed socket ends and is joined by fillet welds at each end. It is designed for high-pressure piping systems where threaded connections are not suitable and a permanent, leak-resistant joint is required. Licensed pipefitters and welding professionals install this fitting in industrial, commercial, and process piping applications where carbon steel construction and Class 3000 pressure ratings are specified.

This coupling is used in 1/4 inch nominal pipe size configurations across a range of piping systems including steam, hydraulic, and process fluid lines. The socket weld design makes it well suited for small-bore, high-pressure runs where full-penetration joints are needed. It fits into systems assembled per ASME B16.11 forged fittings standards, which governs socket weld and threaded fittings in this pressure class.

Key Features

• Forged ASTM A105 carbon steel construction for high-pressure service
• 3000-pound pressure class rating suitable for demanding process piping
• Socket weld end connection type for permanent fillet-welded joints
• 1/4 inch nominal pipe size for small-bore piping runs
• Full socket design ensures consistent alignment during weld assembly

Compatibility

Designed as an OEM-style forged socket weld fitting for 1/4 inch nominal pipe in Class 3000 carbon steel piping assemblies conforming to ASME B16.11 standards.

Installation Notes

Installation requires a certified welder or licensed pipefitter. Before beginning work, isolate and depressurize the line and allow it to cool completely. Socket weld fittings require a small gap between the pipe end and socket bottom prior to welding to allow for thermal expansion — consult applicable welding procedures and ASME B31.3 or B31.1 piping codes for gap and fillet weld size requirements. Post-weld inspection should be performed per the applicable code and project specifications.
