2064117 - ESAB Replacement O-Ring .551 ID x .070 CS 70A

Precision Sealing Component for ESAB Equipment

The ESAB 2064117 O-Ring is a critical maintenance component designed to restore the sealing integrity of your industrial welding equipment. Engineered with precise dimensions, this O-ring features an internal diameter (ID) of 0.551 inches and a cross-sectional width (CS) of 0.070 inches. These specific measurements are crucial for ensuring a static or dynamic seal within the designated gland of your machinery or torch assembly. Using an O-ring with incorrect dimensions, even by a few thousandths of an inch, can lead to extrusion, spiral failure, or insufficient compression, resulting in system leaks.

This component is manufactured with a durometer hardness of 70A (Shore A). This standard hardness rating indicates a material that is hard enough to resist extrusion under moderate pressures yet flexible enough to conform to mating surfaces to create an effective gas or fluid barrier. In the context of welding equipment, 70A durometer seals are typically utilized in gas distribution lines, coolant pathways, or torch connections where a reliable seal is necessary to prevent the loss of shielding gas or cooling fluid. Maintaining the integrity of these seals is vital for process stability and equipment longevity.

When servicing industrial equipment, utilizing genuine OEM parts like the ESAB 2064117 ensures material compatibility and dimensional accuracy. Generic O-rings may not possess the specific chemical resistance or thermal properties required for the welding environment, potentially leading to premature degradation. This O-ring is supplied as a single unit, allowing maintenance personnel to procure the exact quantity needed for specific repairs or to stock essential spares for preventative maintenance schedules.
