Fluorosilicone O-Rings (FVMQ) 75 Duro

Fluorosilicone O-Rings 75D (FVMQ) for Aerospace & Automotive Applications

Fluorosilicone is an elastomeric compound most often used in aerospace applications for systems requiring fuel and/or diester-based lubricant resistance up to 392°F. Although generally specified for aerospace use, due to its excellent fuel resistance and high temperature stability, Fluorosilicone is becoming an increasingly popular material for a wider range of sealing applications.

General Information:

  • Use where excellent fluid resistance is needed at extreme low temperature
  • Typically used in aircraft fuel & hydraulic systems
  • Excellent low temperature flexibility
  • Excellent heat resistance
  • Good compression set properties


  • Fuel injectors
  • Quick connects
  • Fuel pumps
  • Fuel tank seals
  • Any seal application dealing with fuels at low temperatures
