37V15 - ESAB 37V15 Gas Lens Insulator for 17/18/26 Series TIG Torches

Optimize Your TIG Torch with the ESAB 37V15 Gas Lens Insulator

The ESAB 37V15 Gas Lens Insulator is a vital component for professional welders looking to utilize gas lens collet bodies on their standard air-cooled or water-cooled TIG torches. Designed to fit the popular 17, 18, and 26 series torches (including WP-17, WP-18, and WP-26 models), this insulator sits between the torch body and the gas lens cup, providing the necessary electrical isolation and gas seal required for precision welding.

Unlike standard collet body setups which use a different insulator, the 37V15 is specifically engineered to accommodate the larger diameter of gas lens collet bodies. Gas lenses are preferred in high-quality fabrication because they smooth out the shielding gas flow, creating a laminar stream that protects the weld pool more effectively than turbulent flow from standard collets. This allows the welder to extend the tungsten electrode further out for better visibility and access into tight corners without sacrificing shield coverage.

Manufactured by ESAB to strict tolerances, this insulator is built from high-temperature composite materials capable of withstanding the intense heat generated during heavy-duty welding applications. Whether you are welding stainless steel, aluminum, or mild steel, ensuring your torch is equipped with a high-quality insulator like the 37V15 prevents arc wandering, gas leakage, and potential damage to your torch head. It is a small but indispensable part of a high-performance TIG setup.
