0367581881 - ESAB PKB 250 Replacement Swan Neck 45 Degree

Technical Overview of the ESAB PKB 250 Swan Neck

The ESAB 0367581881 is a specialized replacement swan neck designed exclusively for the PKB 250 series of fume extraction MIG guns. This component is critical for the proper operation of the welding torch, serving as the primary conduit for the welding wire, shielding gas, and the extraction of hazardous welding fumes. The neck features a precise 45-degree curvature, engineered to match the original specifications of the PKB 250 system, ensuring that the internal liner sits correctly without kinking, which promotes smooth wire feedability and reduces the risk of bird-nesting.

Constructed from high-grade conductive alloys, this swan neck is built to handle the thermal stresses associated with air-cooled welding applications up to the amperage rating of the PKB 250 (typically 250A CO2 / 200A Mixed Gas). The design incorporates the necessary channels for vacuum suction, allowing the fume extraction system to capture particulate matter directly at the source—the weld pool. Maintaining the integrity of the swan neck is vital for safety compliance; a damaged or clogged neck can significantly reduce capture velocity, exposing the operator to higher levels of particulate.

Installation of the 0367581881 module restores the torch to factory standards. It interfaces seamlessly with the PKB handle and cable assembly, ensuring a gas-tight seal for shielding gases and a vacuum-tight seal for the extraction shroud. This OEM part guarantees compatibility with standard ESAB contact tips, tip holders, and gas nozzles designed for the PKB range. Industrial MROs should stock this item to minimize downtime in fabrication environments where fume control is mandatory.
