Parker's Fluorocarbon 75 Durometer O-Ring, Low & High Temperature (VM835-75) has excellent compression set resistance for a low temperature, GLT type of fluorocarbon material.  Designed for AMS-R-83485, the material 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

Chemical resistance
• Mineral oil and grease, ASTM oil No. 1, and IRM 902 and IRM 903 oils
• Non-flammable hydraulic fluids (HFD)
• Silicone oil and grease
• Mineral and vegetable oil and grease
• Aliphatic hydrocarbons (butane, propane, natural gas)
