99W30 - ESAB 99W30 Replacement O-Ring .801 ID x .070 CS (Pack of 5)

Precision Sealing for TIG Applications

The ESAB 99W30 O-Ring is a critical replacement component designed to maintain the integrity of your welding torch assembly. Manufactured to precise tolerances, this O-ring features an internal diameter (ID) of 0.801 inches and a cross-section (CS) thickness of 0.070 inches. These dimensions are specific to select ESAB, L-Tec, and Linde Heliarc TIG torches, ensuring a perfect fit that generic O-rings often fail to provide.

Constructed from high-quality elastomeric material, the 99W30 is engineered to withstand the thermal cycling and environmental conditions typical of industrial welding. It serves as a vital seal within the torch body or connection points, preventing the escape of shielding gas or the intrusion of atmospheric air. Maintaining the correct pressure and flow of inert gas is essential for high-quality TIG welding, and a compromised O-ring is a frequent point of failure in older equipment.

This product is supplied as a pack of 5, allowing workshops and maintenance technicians to keep spare parts on hand for immediate repair. Regular inspection and replacement of these seals are recommended as part of a preventative maintenance schedule to avoid downtime and ensure consistent weld parameters.
