Product Code:SAE AMS7276
Title:Rings, Sealing, Fluorocarbon (FKM) Rubber, High-Temperature-Fluid Resistant, Low Compression Set, 70 to 80
Issuing Committee:Ams Ce Elastomers Committee
Scope: This specification covers a fluorocabron (FKM) rubber in the form of molded rings. These rings have been used typically for use in contact with air or a variety of fuels, lubricants, and specific hydraulic fluids from -15 to +260 degrees C (-5 to +500 degrees F). The very-low compression set of these rings gives longer life than rings of other fluorocarbon rubbers, such as AMS 7280, at equal temperatures. The cross-section of such rings is usually not over 0.275 inch (6.98 mm) in nominal diameter or thickness.
