V0709-90 Datasheet

Parker V0709-90 is a 90 shore A black FKM compound developed to meet AMS-R-83248 Type 1, Class 2 and AMS 7259 requirements, offering high performance sealing in aerospace and industrial environments. This material provides strong resistance to petroleum, mineral, and vegetable oils, along with compatibility with aromatic and chlorinated hydrocarbons, making it well suited for fuel systems, high vacuum applications, and aggressive chemical exposure. It also demonstrates excellent resistance to ozone, weathering, and aging, supporting long-term durability in O-rings and gaskets operating between approximately -150°F and 400°F. Parker V0709-90 can be compared to other aerospace grade FKM materials with similar specifications when evaluating equivalent compounds for critical sealing applications.

 

FKM, commonly known under trade names like Viton®, is a high performance fluoroelastomer widely used in O-rings and gaskets where chemical resistance and elevated temperature capability are required. These materials are known for their stability in fuels, oils, and many harsh chemicals, while maintaining good compression set resistance and long service life. FKM compounds are frequently used in aerospace, automotive, oil and gas, and chemical processing industries, though they are typically not recommended for hot water, steam, or certain polar solvents. Their balance of thermal and chemical resistance makes them a preferred choice for demanding sealing environments where reliability is critical.
