Rubber: Fluorocarbon Elastomer (FKM) Low Temperature Sealing Tg -40 °F (-40 °C) 70 to 80 Type ‘A’ Hardness For Elastomeric Seals in Aircraft Engine Oil, Fuel and Hydraulics Systems
AMS7379A
This specification covers a fluorocarbon (FKM) rubber in the form of O-rings, compression seals, O-ring cord, and molded-in-place gaskets for aeronautical and aerospace applications. For sheet, strip, tubing, extrusions, and molded shapes use the AMS3353 specification which is intended for that use.
Rationale:
Specification has been revised to change the glass transition testing method from ASTM D3418 to ASTM D7426, as well as a general update of the specification to the latest format.
