81Z24 - ESAB 81Z24 Water Jacket Gasket for HW-18 / PTW-18 TIG Torches

Reliable Sealing for Water-Cooled TIG Torches

The ESAB 81Z24 Water Jacket Gasket is a critical replacement component designed for the maintenance and repair of heavy-duty water-cooled TIG torches, specifically the renowned HW-18 and PTW-18 series. In high-amperage welding applications, water-cooled torches rely on a sealed circulation system to dissipate heat effectively. The water jacket gasket acts as the primary barrier, ensuring that coolant flows around the torch head without leaking into the shielding gas stream or onto the workpiece.

Over time, thermal cycling and exposure to coolant additives can degrade rubber seals, leading to brittleness or cracking. A compromised gasket can result in coolant leaks, which not only cause mess and waste but can also contaminate the weld pool, leading to porosity and defects. Replacing the 81Z24 gasket during routine maintenance or when leaks are detected is essential for preserving the longevity of your torch and the quality of your welds.

This genuine ESAB part is manufactured to precise tolerances, ensuring a snug and leak-proof fit. It is compatible with legacy Linde and L-Tec HW-18 models as well as modern ESAB PTW-18 torches. Whether you are rebuilding an older torch or performing preventative maintenance on your shop's primary equipment, this gasket provides the reliability professional welders demand.
