Parker VA163-80 is an 80 shore A black FKM compound formulated with internal lubrication to reduce friction and improve wear performance in demanding sealing applications. This material is ideal for O-rings and gaskets used in dynamic systems where reduced stick-slip and smoother operation are critical, such as hydraulic equipment and moving assemblies. It provides excellent resistance to petroleum, mineral, and vegetable oils, along with compatibility with aromatic and chlorinated hydrocarbons, while maintaining durability in high vacuum environments. With a typical service temperature range of approximately -15°F to 400°F, VA163-80 offers strong resistance to ozone, weathering, and aging, and can be compared to other internally lubricated 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. Internally lubricated FKM compounds incorporate additives to lower surface friction, improve wear characteristics, and enhance performance in dynamic sealing applications. These materials are commonly used in industrial, automotive, and aerospace systems where both chemical resistance and smooth operation are required. 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 sealing performance.
