326P274755 - ESAB Yellow PTFE Liner for 1.2mm Aluminum Wire

Smooth Wire Feeding for Aluminum Welding

The ESAB Liner 7W Yellow is a specialized PTFE (Polytetrafluoroethylene) conduit designed to solve the common challenges associated with welding soft wires. When working with aluminum or stainless steel MIG wire, standard steel liners can cause excessive friction, wire shaving, and the dreaded "bird-nesting" at the drive rolls. This liner features a low-friction Teflon composition that allows soft wires to glide smoothly through the torch cable, ensuring a stable arc and consistent weld bead.

Color-coded Yellow for quick identification, this liner is sized specifically for 1.2mm (0.045") diameter wires. It is an essential accessory for fabricators working in the automotive, marine, or aerospace industries where aluminum welding is prevalent. By reducing drag within the gun cable, the ESAB PTFE liner helps maintain constant wire feed speeds, which is critical for high-quality pulsed MIG or standard spray transfer processes.

Key Benefits

• Reduced Friction: The smooth PTFE interior minimizes drag, preventing soft aluminum wire from buckling.
• Material Purity: Unlike steel liners, PTFE does not contaminate the wire surface, maintaining the integrity of stainless and aluminum welds.
• Easy Identification: The bright yellow jacket allows operators to instantly verify they have the correct liner size installed for their 1.2mm wire setup.

Upgrade your MIG gun setup with genuine ESAB parts to ensure longevity and performance. Whether you are repairing aluminum trailers or fabricating stainless steel tanks, this liner provides the reliability professional welders demand.
