61N22 - ESAB ST-12 TIG Torch Sleeve Insulator 61N22

Genuine ESAB 61N22 Sleeve Insulator for ST-12 Torches

Maintain the precision and safety of your TIG welding operations with the ESAB 61N22 Sleeve Insulator. Designed exclusively for the heavy-duty ST-12 TIG torch (formerly known under the Linde and L-Tec brands), this component plays a pivotal role in the torch's assembly. The sleeve insulator acts as a critical barrier, electrically isolating the current-carrying components of the torch head from the handle and other non-conductive parts. Without a functioning insulator, welders risk internal arcing, torch damage, and potential safety hazards.

The ST-12 torch is renowned for its durability in industrial environments, and the 61N22 insulator is built to match that standard. Manufactured from high-grade, heat-resistant materials, it is engineered to withstand the intense thermal cycles associated with high-amperage TIG welding. Over time, insulators can become brittle, cracked, or carbon-tracked due to heat exposure and spatter. Replacing a worn insulator with this genuine ESAB part restores the dielectric strength of the torch assembly, ensuring a stable arc and consistent gas shielding.

At Josef Gas, we understand that using OEM parts is essential for equipment longevity. This sleeve insulator fits perfectly within the ST-12 head assembly, ensuring no gaps that could lead to high-frequency leakage or shielding gas turbulence. Whether you are performing critical aerospace welds or heavy industrial fabrication, ensuring your torch insulation is intact is the first step toward a quality weld.

Key Benefits of the 61N22 Insulator
