53N65 - 53N65 TIG Torch Nozzle Gasket / Insulator for WP-20

Reliable Insulation for Precision TIG Welding

The ESAB 53N65 Insulator is a fundamental component designed for the HW-20, WP-9, WP-20, and WP-25 series TIG welding torches. In the precise world of Gas Tungsten Arc Welding (GTAW), maintaining the integrity of your torch assembly is paramount for weld quality and operator safety. This insulator, often referred to as a nozzle gasket, serves as the critical barrier between the electrically live components of the torch head and the gas nozzle (cup).

Manufactured to strict tolerances, this ESAB replacement part ensures a perfect fit, which is essential for creating an airtight seal. A compromised insulator can lead to shielding gas leaks, resulting in porosity in the weld and increased gas consumption. Furthermore, the 53N65 prevents high-frequency current from arcing to the nozzle, which can damage the torch and disrupt the welding arc. Constructed from high-temperature resistant materials, it is built to withstand the thermal cycling and radiant heat generated during extended welding sessions.

Whether you are performing maintenance on an industrial production line or restocking a fabrication shop, the ESAB 53N65 offers the reliability professionals demand. It is compatible with standard collet bodies and gas lens setups typically found on 2-series (9/20) torches, making it a versatile spare part for your inventory.
