0700300842 - ESAB RT 82 W TIG Torch Nozzle Insulator Black

Reliable Insulation for Precision TIG Welding

The ESAB Nozzle Insulator Black (0700300842) is a critical replacement component designed specifically for the RT 82 W water-cooled TIG welding torch. In high-precision TIG applications, maintaining the integrity of your torch's front-end consumables is essential for arc stability and safety. This insulator serves as the barrier between the electrically charged components of the torch head and the gas nozzle, preventing unwanted arcing and ensuring the shielding gas is directed properly.

Manufactured to ESAB's exacting standards, this black insulator is crafted from high-heat resistant materials capable of withstanding the intense thermal cycles associated with water-cooled TIG welding. Over time, insulators can become brittle, cracked, or coated in spatter, which compromises the gas seal and electrical safety of the torch. Replacing a damaged insulator with this genuine OEM part restores the torch to factory specifications, ensuring a tight seal and consistent performance.

Whether you are performing maintenance on your shop's equipment or troubleshooting an unstable arc, the ESAB 0700300842 is the correct fit for the RT 82 W series. It installs easily, seating firmly to prevent gas turbulence that can lead to weld porosity. Trust genuine ESAB parts to extend the lifespan of your welding equipment and maintain the high-quality results your projects demand.
