60N79 - ESAB 60N79 TIG Torch Nozzle Gasket / Insulator (Pack of 2)

Technical Overview of ESAB 60N79

The ESAB 60N79 is a specialized nozzle gasket, often referred to as a spacer or insulator, designed for use with standard TIG welding torches. This component is critical for the assembly of the torch front end, specifically fitting the 17, 18, and 26 series torch bodies (often designated as WP-17, WP-18, WP-26). The gasket serves as the interface between the torch body and the ceramic cup (nozzle), ensuring that the high-voltage welding current is isolated from the shielding gas nozzle, provided the nozzle is not conductive, and more importantly, sealing the gas path to prevent atmospheric contamination.

Manufactured to ESAB's stringent quality standards, this part corresponds to the industry-standard reference number 60N79. It is typically constructed from high-dielectric strength materials such as Teflon (PTFE) or specialized heat-resistant rubber compounds, capable of withstanding the radiant heat generated during the GTAW process. This specific SKU is supplied as a pack of two, allowing for immediate replacement and a spare for inventory management. It is designed for use with standard collet bodies rather than gas lens setups, which typically require a different insulator geometry.

Proper installation of the 60N79 is essential for the safe operation of the TIG torch. A compromised gasket can lead to high-frequency leakage, where the arc initiates at the wrong point, or shielding gas turbulence caused by leaks at the cup threads. This component ensures the structural integrity of the nozzle attachment and maintains the laminar flow of inert gas required for high-quality welds.
