Parker VB185-70 is a 70 shore A black FKM compound formulated for applications requiring strong acid resistance and reliable performance in steam and chemically aggressive environments. This material offers excellent compatibility with oils, fuels, and a wide range of hydrocarbons, along with good resistance to nonflammable hydraulic fluids and high vacuum conditions. It also provides strong resistance to ozone, weathering, and aging, making it a dependable choice for O-rings and gaskets used in industrial processing, chemical handling, and sealing systems exposed to elevated temperatures. With a service temperature range of approximately -15°F to 400°F, VB185-70 meets ASTM D2000 M2HK707 requirements and can be compared to other acid-resistant FKM compounds when evaluating equivalent 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 aggressive chemicals is essential. Specialized grades such as acid-resistant FKM compounds are engineered to perform in harsher chemical environments than standard FKM, including exposure to certain acids and steam conditions. These materials are commonly used in chemical processing, oil and gas, and industrial sealing applications where durability and long service life are required. While highly versatile, FKM materials are generally not recommended for strong bases, amines, or certain polar fluids, making careful material selection critical.
