Parker VW153-75 is a 75 shore A brown FKM compound designed as a general purpose sealing material for applications requiring dependable chemical resistance and thermal stability. This material performs well in O-rings and gaskets exposed to petroleum, mineral, and vegetable oils, as well as aromatic and chlorinated hydrocarbons, making it suitable for fuel systems, industrial equipment, and high vacuum environments. It also offers strong resistance to ozone, weathering, and aging, supporting long-term sealing reliability in demanding conditions. With a typical service temperature range of approximately -15°F to 400°F, VW153-75 can be compared to other general purpose FKM compounds when evaluating equivalent materials.
FKM, commonly referred to as Viton®, is a high performance fluoroelastomer widely used in O-rings and gaskets where resistance to fuels, oils, and elevated temperatures is essential. General purpose FKM materials provide a balanced combination of chemical resistance, durability, and thermal performance across a wide range of industrial applications. These compounds are commonly used in automotive, aerospace, oil and gas, and chemical processing environments where reliable sealing is critical. While highly versatile, FKM materials are generally not recommended for hot water, steam, or certain polar solvents, making proper material selection important for long-term performance.
