105Z26 - ESAB 105Z26 TIG Torch Insulator Gasket for 9/20 Series

Precision Fit for Superior Arc Control

As a TIG welder, you know that the devil is in the details. A worn or cracked insulator might seem like a small issue, but it can wreak havoc on your weld quality. The ESAB 105Z26 Insulator Sleeve is designed to fit your HW-9, WP-9, or WP-20 torch perfectly, acting as the essential seal between your torch body and the alumina cup. When this gasket is in good condition, it ensures that your shielding gas flows smoothly without leaking out the back of the cup, which is critical for preventing porosity and maintaining a clean, stable arc.

This insulator is built from high-temperature polymer material capable of withstanding the intense radiant heat of TIG welding. Unlike cheaper alternatives that may become brittle and crack after a few heating and cooling cycles, the 105Z26 retains its structural integrity, ensuring you don't encounter unexpected arcing or 'hf leakage' that can startle you or damage the workpiece. It also protects the threads on your torch head, preventing them from seizing up due to heat expansion or debris accumulation.

Installation is straightforward—simply unscrew your cup, remove the old gasket, and thread this one on. It seats firmly against the torch body, providing a solid platform for your gas lens or collet body. Whether you are welding thin aluminum in an aerospace application or stainless steel pipe, having a fresh insulator ensures your gas coverage is optimized and your torch is safe to handle. This pack contains two insulators, so you can swap one out immediately and keep a spare in your toolbox for the next time you need it.
