V1289-75 Low Temperature FKM (Aerospace)


Low Temperature Performance

Parker’s V1289-75 fluorocarbon compound offers the best low temperature sealing performance of any fluorocarbon rubber material available in the market.

Low temperature performance has long been the Achilles’ heel of fluorocarbon elastomer technology. Standard fluorocarbon copolymer compounds seal down to about -15°F (-26°C). Low temperature (GLT-type) fluorocarbon compounds offer low temperature flexibility at Tg of -22°F (-30°C) and improved HTS oil stability but sacrifice compression set. With a Tg of -40°F (-40°C), V1289-75 offers reliable dynamic sealing down to -40°F and static sealing down to -55°F (-48°C) in the most demanding seal applications.
