0457969002 - ESAB PTFE/Ceramic MIG Liner 1.0-1.2mm Bulk Roll (50m)

Premium Bulk Wire Feeding Solution

The ESAB PTFE/Ceramic Liner (Part Number 0457969002) is a high-performance consumable designed to optimize the feeding of welding wires in MIG/MAG applications. Supplied in a substantial 50-meter bulk roll, this liner is an essential inventory item for industrial fabrication shops that require flexibility and cost-efficiency in their maintenance operations. By purchasing in bulk, facilities can cut liners to exact custom lengths for various torch assemblies, reducing waste and ensuring that a replacement is always on hand.

This specific liner is engineered for wire diameters ranging from 1.0mm to 1.2mm (approximately 0.040" to 0.045"). The core material construction combines Polytetrafluoroethylene (PTFE) with ceramic reinforcements. Pure PTFE is renowned for its extremely low coefficient of friction, which is critical when feeding soft wires such as aluminum or stainless steel that are prone to buckling or "bird-nesting." However, pure PTFE can be soft and wear quickly. The addition of ceramic components enhances the mechanical strength and abrasion resistance of the liner, extending its service life without compromising the smooth feeding characteristics required for precision welding.

Proper liner maintenance is crucial for arc stability. A worn or clogged liner is a leading cause of erratic wire feeding, burn-backs, and poor weld quality. The ESAB PTFE/Ceramic liner ensures that wire travels smoothly from the drive rolls to the contact tip, minimizing drag and preventing contamination of the wire surface. This is particularly important in aluminum welding, where even minor friction can cause shavings that clog the liner. This product represents ESAB's commitment to providing professional-grade solutions for demanding industrial environments.
