Description / Abstract:


This specification covers two classes (durometers) of tetrafluoroethylene/propylene rubber (FEPM) in the form of sheet, strip, tubing, extrusions, and molded shapes. For molded rings, compression seals, O-ring cord, and molded-in-place gaskets for aeronautical and aerospace applications, use the AMS7255 or AMS7256 specification, as appropriate.


These products have been used typically for components requiring continuous operation in dry air, hydraulic fluids, and synthetic engine oils at temperatures from -5 to +232 °C (+23 to 450 °F) or in high pH chemical decontamination solutions, but usage is not limited to such applications.


Product is classified as follows:

Class 1 – 70 to 80 Durometer “A” hardness

Class 2 – 85 to 95 Durometer “A” hardness

The class supplied shall be the class ordered
