85W87 - ESAB 85W87 Replacement O-Ring - 1.984 ID x 0.139 CS CR 70A

Precision Sealing with the ESAB 85W87 O-Ring

The ESAB 85W87 O-Ring is a precision-engineered sealing component designed to maintain the operational integrity of ESAB welding equipment. This O-ring features specific dimensions with an Inner Diameter (ID) of 1.984 inches and a Cross Section (CS) of 0.139 inches. These exact measurements are critical for ensuring a static or dynamic seal within the designated assembly, preventing the leakage of gases or fluids that are vital for the welding process.

Constructed from Chloroprene Rubber (CR), widely known as Neoprene, this seal offers superior resistance to a broad range of industrial challenges. The material is chemically resistant to oils, greases, and mild acids, while also providing excellent stability against ozone and weathering. This makes the 85W87 particularly suitable for equipment that operates in varied shop environments where exposure to contaminants is likely.

The O-ring is manufactured to a 70 Durometer (Shore A) hardness. This standard hardness rating ensures the seal is firm enough to resist extrusion under pressure while remaining flexible enough to conform to mating surfaces and accommodate slight irregularities. Whether utilized in gas distribution systems, torch assemblies, or internal machine connections, this genuine ESAB part meets strict OEM specifications for tolerance and material quality.

Using authentic replacement parts like the 85W87 is essential for preserving the safety and efficiency of industrial machinery. Generic seals may lack the precise dimensional tolerances or material composition required for long-term performance, leading to premature failure. Trust in ESAB's engineering to provide the reliability needed for continuous industrial operations.
