Parker’s Fluorocarbon 75 Durometer O-Ring, Low & High Temperature (VM125-75) has best in class compression set resistance for a low temperature, GLT type of fluorocarbon material. Formulated for the stringent high temperature requirements of AMS 7287, the material also exhibits outstanding HTS turbine oil compatibilty, outstanding jet fuel compatibity, and outstatnding hydraulic oil resistance.
• Heat resistance – Up to 204°C (400°F) and higher temperatures with shorter life expectancy
• Cold flexibility – Down to -40°C (-40°F) for static applications and -26°C (-15°F) for dynamic applications
