0700300320 - ESAB PTFE Liner 1.0-1.2mm 3.5m (5-Pack)

High-Performance PTFE Liners for Aluminum Welding

The ESAB PTFE Liner (0700300320) is a critical component for fabricators working with soft welding wires, particularly aluminum and stainless steel. Unlike standard steel liners, which can cause friction, shaving, and contamination of soft wires, this Polytetrafluoroethylene (PTFE) liner offers an exceptionally low coefficient of friction. This ensures smooth, consistent wire feeding through the torch cable, minimizing the risk of burn-backs and erratic arcs caused by feedability issues.

Designed specifically for wire diameters ranging from 1.0mm (0.040") to 1.2mm (0.045"), this liner provides the precise internal clearance necessary to support the wire column without binding. The 3.5-meter length is suitable for standard MIG gun assemblies, allowing for easy installation and replacement. By using a dedicated PTFE liner, operators can maintain the purity of the weld deposit, as it prevents the introduction of steel shavings that can occur when using incorrect liners with aluminum wire.

This product is supplied as a pack of 5, making it an excellent choice for industrial environments where uptime is critical. Regular liner replacement is a key maintenance practice for high-quality aluminum welding, and having stock on hand ensures that production interruptions are minimized. Whether used in automotive fabrication, marine repair, or general manufacturing, the ESAB PTFE liner delivers the reliability required for precision MIG welding.
