VT80BK20 is an 80 shore A black FKM Type GF compound engineered for applications requiring enhanced chemical resistance and higher mechanical strength. This material is well suited for O-rings and gaskets exposed to steam, acids, aromatic hydrocarbons, and aggressive industrial media, while maintaining strong performance in fuels and oils. Its higher durometer improves extrusion resistance and durability in higher pressure environments, while still providing excellent resistance to heat, ozone, weathering, and aging. With a service temperature range of -16°C to 225°C, VT80BK20 meets ASTM D2000 M2HK814 requirements and can be compared to Parker V1274-80 when evaluating equivalent GF-type FKM materials.
FKM, commonly referred to as Viton®, is a high performance fluoroelastomer widely used in O-rings and gaskets where resistance to heat, fuels, and harsh chemicals is essential. GF-type FKM compounds are formulated to provide improved resistance to steam, acids, and chemically aggressive environments compared to standard grades. Higher durometer variants like 80A are commonly selected for applications requiring improved extrusion resistance and mechanical strength under pressure. While highly versatile, FKM materials are generally not recommended for certain polar solvents or extreme steam conditions beyond their limits, making proper material selection important.
