VT80BK00 is an 80 shore A black FKM Type A compound designed as a durable, cost-effective solution for general purpose sealing applications. Its higher durometer provides improved extrusion resistance compared to lower hardness grades, making it well suited for O-rings and gaskets used in higher pressure systems and tighter clearances. The material offers excellent resistance to heat, fuels, oils, and a wide range of industrial chemicals, along with strong durability against ozone, weathering, and aging. With a service temperature range of -26°C to 225°C, VT80BK00 meets ASTM D2000 M6HK810 requirements and can be compared to Parker compounds such as V1164-75, V1476-75, and V1475-75 for equivalent performance.
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. Type A FKM materials are general purpose grades that provide a strong balance of chemical resistance, thermal stability, and cost efficiency. Higher durometer variants like 80A are often selected for applications requiring improved mechanical strength and resistance to extrusion under pressure. 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 success.
