VT75BU04 is a 75 shore A blue FKM Type A compound that is both FDA compliant and metal detectable, making it ideal for critical food and pharmaceutical sealing applications. This material is specifically designed for O-rings and gaskets used in processing environments where contamination detection is essential, allowing fragments to be identified by metal detection systems. It provides 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 -20°C to 225°C, VT75BU04 meets ASTM D2000 M2HK707 requirements and delivers reliable performance in regulated and high visibility applications.
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. FDA compliant and metal detectable FKM compounds are engineered for use in food, beverage, and pharmaceutical industries, combining chemical resistance with safety and traceability features. These materials maintain strong sealing integrity over time while meeting regulatory requirements for contact and contamination control. While highly versatile, FKM compounds are generally not recommended for hot water, steam, or certain polar solvents, making proper selection important for long-term sealing success.
