2064064 - ESAB Replacement O-Ring - .114 ID x .070 CS

Precision Sealing for Industrial Welding Equipment

The ESAB 2064064 O-Ring is a critical maintenance component designed to restore the integrity of gas sealing systems within professional welding setups. Manufactured to precise tolerances, this O-ring features an Inner Diameter (ID) of 0.114 inches and a Cross Section (CS) of 0.070 inches, corresponding to the standard AS568-006 dash number. In pneumatic and gas-handling applications, even microscopic imperfections in sealing components can lead to pressure drops, gas wastage, or hazardous leaks. This replacement part is engineered to provide a consistent compression seal, ensuring that regulators, torches, and flowmeters operate within their specified safety parameters.

Material composition is paramount in welding environments where components may be exposed to various shielding gases, fluctuating pressures, and residual contaminants. While specific elastomer formulations can vary by batch, ESAB replacement parts are typically constructed from high-grade synthetic rubber compounds such as Nitrile (Buna-N) or Viton, selected for their resilience and resistance to compression set. This ensures that the O-ring maintains its elastic memory over time, preventing the flattening effect that often compromises older seals. Proper installation of the 2064064 O-ring helps maintain the closed-loop efficiency of shielding gas delivery systems, directly contributing to weld quality by preventing atmospheric contamination.

Maintenance personnel and equipment technicians should regularly inspect O-rings during routine service intervals. Signs of wear such as cracking, brittleness, or deformation indicate the immediate need for replacement. Using genuine or specification-matched parts like the ESAB 2064064 guarantees that the dimensional fit is exact, eliminating the guesswork associated with generic bulk O-rings that may not meet the strict tolerances required for high-pressure gas equipment. Whether used in a regulator seat, a torch valve, or a hose connection, this small component plays a vital role in the overall reliability of the welding station.
