Rings, Sealing, Silicone (VSI) Rubber, Heat-Resistant, Low Compression Set, 70-80 ( Reaffirmed: Apr 2001 )
This specification covers a silicone (VSI) rubber in the form of molded rings. These rings have been used typically as sealing rings for service from -65 to +260 degrees C (-85 to +500 degrees F) in contact with air, but usage is not limited to such applications. The cross-section of such rings is usually not over 0.275 in. (6.98 mm) in diameter or thickness.
