0457969882 - ESAB PTFE Liner 1.0-1.2mm x 3m for PSF Torches

Optimize Your Aluminum Welding with ESAB PSF Teflon Liners

The ESAB PSF Teflon Liner (0457969882) is a critical component for welders working with soft filler metals such as aluminum and stainless steel. Designed specifically for ESAB PSF series MIG guns, this 3-meter liner is manufactured from high-grade Polytetrafluoroethylene (PTFE), commonly known as Teflon. Unlike coiled steel liners, which can shave soft wires and cause friction-related feeding issues, this smooth-bore PTFE liner ensures a consistent and uninterrupted wire feed.

Feeding aluminum wire through a MIG torch presents unique challenges due to the material's softness and tendency to buckle (bird-nest) if it encounters resistance. The ESAB PSF Teflon liner minimizes this resistance, allowing the drive rolls to push the wire smoothly to the contact tip. This specific liner is sized for wire diameters ranging from 1.0mm (0.040") to 1.2mm (0.045"), covering the most common sizes used in light to medium industrial fabrication.

Installing the correct liner is the first step in troubleshooting erratic arcs and burn-backs. By choosing genuine ESAB parts, you ensure that the liner dimensions perfectly match your PSF torch cable, preventing gas leaks or fitment issues. Whether you are fabricating aluminum boat hulls, repairing trailers, or performing precision stainless work, this liner provides the reliability professional welders demand.

Key Benefits

• Low Friction: PTFE material allows soft wires to slide easily, reducing strain on the wire feeder.


• Precision Fit: Engineered for ESAB PSF torches for a hassle-free installation.


• Versatile Sizing: Accommodates both 1.0mm and 1.2mm wires effectively.
