Rings, Sealing, Phosphonitrilic Fluoroelastomer (Fz) Aviation Fuel Resistant 65-75 Shore A
This specification covers a phosphonitrilic fluoroelastomer (FZ) in the form of molded rings. Primarily for use in aircraft fuels systems operating from -55 to +150 degrees C (-67 to 302 degrees F).
The specification was made non-current when Ethyl discontinued manufacturing of the base elastomer FZ. MST (Materials Science Technology) began FZ production in September 2009.
