This document has been declared “Stabilized” and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist.This specification covers a polytetrafluoroethylene (PTFE) modified fluorosilicone (FVMQ) rubber in the form of molded shapes, molded rings (ASTM D 1414), and compression seals.These products have been used typically for parts requiring resistance to jet fuel and lubricating oils, but usage is not limited to such applications. Generally, products are usable over a temperature range of -60 to +150 degrees C (-76 to +302 degrees F); the high tear resistance improves installation characteristics and the high tensile stress (modulus) enhances extrusion resistance. Each application, however, has to be considered individually.
