Parker VW252-65 is a 65 shore A green FKM compound engineered for low swell performance in fuel and hydrocarbon environments. This material is well suited for O-rings and gaskets used in fuel systems, offering improved dimensional stability when exposed to fuels, petroleum oils, and aggressive hydrocarbons. Its lower durometer enhances conformability in tight tolerance grooves and low pressure applications, while maintaining excellent resistance to aromatic and chlorinated hydrocarbons, high vacuum conditions, and environmental aging. With a typical service temperature range of approximately -15°F to 400°F, VW252-65 can be compared to other low swell FKM compounds when evaluating equivalent sealing 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. Low swell FKM materials are specifically formulated to minimize volume change in aggressive fuel blends, helping maintain sealing integrity over time. These compounds are commonly used in automotive, aerospace, oil and gas, and industrial applications where both chemical compatibility and dimensional stability are critical. While highly versatile, FKM materials are generally not recommended for hot water, steam, or certain polar solvents, making proper material selection important.
