Fluorosilicone O-Rings (FVMQ) 70 Duro

Fluorosilicone O-Rings 70D (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.
