VT90BK90 is a 90 shore A black FKM Type A compound qualified to AMS-7259 and MIL-R-83248A Type 1 Class 2, making it a widely used aerospace and military specification sealing material. This compound delivers excellent resistance to fuels, oils, and a broad range of chemicals, along with strong performance under elevated temperatures and harsh environmental conditions. Its high durometer enhances extrusion resistance, making it ideal for O-rings and gaskets used in high pressure systems, fuel handling equipment, and aerospace components. With a service temperature range of -26°C to 225°C, VT90BK90 can be compared to Parker compounds such as V0709-90 and VA153-90 when evaluating equivalent MIL-spec FKM 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. MIL-spec and AMS-qualified FKM compounds are designed to meet strict aerospace and defense requirements, ensuring consistent performance and reliability in critical applications. These materials are commonly used in aircraft systems, fuel systems, and industrial equipment where durability and compliance are required. While highly versatile, FKM materials are generally not recommended for hot water, steam, or certain polar solvents, making proper material selection critical for long-term sealing performance.
