0366549889 - ESAB PSF Steel MIG Liner 1.4mm x 4.5m

Restore Peak Performance to Your ESAB PSF Torch

Is your MIG wire stuttering or feeding unevenly? It might be time to replace your liner. The ESAB PSF Steel Liner 1.4mm x 4.5m is the authentic replacement part you need to get your ESAB PSF MIG gun back to operating at 100%. Over time, liners become clogged with copper dust, dirt, and debris from the shop floor, or they can develop kinks that restrict wire movement. Installing a fresh, high-quality steel liner is one of the most cost-effective ways to instantly improve your welding experience.

Designed for the professional welder, this liner features a robust steel spiral construction that withstands the rigors of daily industrial use. It is specifically engineered for 4.5-meter (15 ft) torch cables, providing full-length protection and guidance for your welding wire. The 1.4mm internal diameter is optimized for the most common wire sizes used in general fabrication—0.040" and 0.045" (1.0mm - 1.2mm). This precise fit reduces the "play" inside the liner, ensuring the wire hits the contact tip center every time for a stable, focused arc.

Don't let a worn-out liner compromise your weld quality or cause frustrating downtime. This liner is compatible with the widely used PSF series guns, known for their ergonomic design and durability. Whether you are welding structural steel, automotive parts, or heavy machinery, relying on genuine ESAB consumables ensures your equipment performs exactly as the manufacturer intended. Swap out your old, dirty liner with this brand-new ESAB steel liner and notice the difference in feed smoothness immediately.
