2064116 - ESAB Silicone O-Ring .239 ID x .070 CS - 70A Hardness

Precision Sealing for Industrial Equipment

The ESAB 2064116 O-Ring is a critical component designed for precision sealing within welding machinery and torch assemblies. Manufactured to exact OEM specifications, this O-ring features an Inner Diameter (ID) of 0.239 inches and a Cross Section (CS) width of 0.070 inches. These dimensions are maintained with tight tolerances to ensure a proper interference fit within the gland, preventing fluid or gas bypass under pressure.

Material selection is paramount in industrial welding applications where components are frequently exposed to thermal cycling. This O-ring is fabricated from high-quality Silicone, a polymer renowned for its wide temperature range and excellent resistance to ozone, UV light, and weathering. Unlike standard Buna-N (Nitrile) O-rings which may harden or crack under extreme heat, silicone maintains its elastomeric properties, ensuring consistent sealing performance over time.

The 70A Durometer hardness rating places this O-ring in the standard range for static and dynamic sealing applications. A 70 Shore A hardness provides enough resistance to extrusion while remaining flexible enough to conform to surface irregularities in the mating parts. This balance is essential for maintaining a hermetic seal in gas distribution systems, coolant lines, and torch head assemblies where vibration and thermal expansion are factors. Utilizing genuine ESAB replacement parts like the 2064116 ensures that the chemical compatibility and physical dimensions align perfectly with the engineering requirements of your ESAB equipment.

Engineers and maintenance technicians understand that the failure of a single O-ring can lead to system inefficiencies, such as shielding gas leaks that compromise weld quality or coolant leaks that risk equipment overheating. By choosing this specification-grade silicone O-ring, you are investing in the reliability and longevity of your welding infrastructure.
