2114581 - ESAB Replacement O-Ring - Neoprene 70A - 2.114 ID

Technical Specification: ESAB 2114581 Neoprene O-Ring

The ESAB 2114581 is a precision-engineered sealing component designed to meet the rigorous demands of industrial welding equipment. Manufactured from high-quality Neoprene (polychloroprene), this O-ring offers a balanced suite of physical properties, making it an ideal choice for general-purpose sealing within welding machine assemblies, wire feeders, and gas distribution systems. Neoprene is renowned for its chemical stability and maintains flexibility over a wide temperature range, ensuring consistent performance in variable workshop environments.

This specific O-ring features a Durometer hardness of 70 Shore A (70A). This is the industry standard for most static and dynamic sealing applications, providing the necessary resistance to extrusion under pressure while retaining enough compressibility to conform to surface irregularities in the mating gland. The 70A hardness rating ensures that the seal does not deform excessively under load, maintaining a tight barrier against gases and fluids.

Dimensionally, the component is manufactured to strict tolerances. It possesses an Inner Diameter (ID) of 2.114 inches and a Cross-Section (CS) width of 0.070 inches. These precise measurements are critical for ensuring the correct squeeze percentage when installed in the hardware groove. Using a generic O-ring with approximate dimensions can lead to seal failure, leakage, or accelerated wear. This genuine ESAB part guarantees the exact geometry required for the intended assembly.

Neoprene's material properties include moderate resistance to petroleum-based oils and fuels, as well as excellent resistance to ozone, sunlight, and oxidation. This makes the 2114581 particularly suitable for external connections or internal components that may be exposed to the ambient shop environment or incidental lubricant contact. By utilizing genuine OEM seals, operators ensure the integrity of their equipment's pneumatic or hydraulic circuits.
