Rings, Sealing, Phosphonitrilic Fluoroelastomer (Fz) Aviation Fuel-Resistant 75-85 Shore A
This specification covers phosphonitrilic fluoroelastomer (FZ) in the form of molded rings. Primarily for use in aircraft fuel 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.
