VT75BK04 Datasheet

VT75BK04 is a 75 shore A black FKM Type A compound designed for 3A sanitary and FDA compliant sealing applications in food, beverage, and processing environments. This material is ideal for O-rings and gaskets used in sanitary systems where resistance to cleaning chemicals, oils, and food media is required, while meeting 3A 18-03 Class I through IV standards. It offers excellent heat resistance, strong chemical compatibility, and durability against ozone, weathering, and aging, ensuring long service life in demanding conditions. With a service temperature range of -26°C to 225°C, VT75BK04 meets ASTM D2000 6HK720 requirements and provides a reliable, cost-effective sealing solution for regulated applications.

 

FKM, commonly referred to as Viton®, is a high performance fluoroelastomer widely used in O-rings and gaskets where resistance to heat, chemicals, and fuels is essential. FDA compliant and 3A sanitary FKM compounds are specifically formulated for use in food and beverage industries, combining chemical resistance with regulatory compliance and long-term durability. These materials are commonly used in processing equipment where cleanliness and resistance to repeated cleaning cycles are critical. While highly versatile, FKM materials are generally not recommended for hot water, steam, or certain polar solvents beyond their limits, making proper material selection important.
