Elastomer: Tetrafluoroethylene/Propylene (FEPM) Hydraulic Fluid and Synthetic Oil Resistant 75 to 90 Hardness
AMS3382D
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.
Rationale:
This revision eliminates corrosion and weathering requirements, modifies periodic testing duration and removes “or equivalent” from hardness requirement. It also incorporates the format of the most current AMS3XXX template.
