Caterpillar Seal O-ring | 8J4351

Description

The 8J4351 Seal O-ring is specifically designed for use in high-temperature environments where it needs to withstand air, fuels, lubricants and hydraulic fluids. It's made from FKM rubber which can handle temperatures ranging from -40 to 150° C. This O-ring provides resistance against air, fuel (including bio-diesel), lubricants and oils. It has a section diameter of 0.139 inches, an inside diameter of 1.734 inches and an outside diameter of 2.012 inches. With a hardness rating of 75 Shore A and a black color code for identification, the O-ring is compatible with diester lubricants, halogenated hydrocarbons (above 100° C) and certain acids but not suitable for applications that require resistance to water or coolant.
