Fluorosilicone O-rings (FVMQ o-rings)

Good general purpose sealing for aerospace and jet fuel applications

Fluorosilicone O-rings from Parker are recommended for general purpose service in aerospace and fuel applications, and provide good high/low temperature performance in sealing fuels and mineral oils. 

Although some of the specific fluorosilicone O-ring compound temperature limits are listed below, common ranges vary between -100 °F to 350 °F. Find your fluorosilicone O-ring size in the O-rings Size Chart.  

Chemical Compatibility can also be viewed using the fluorosilicone O-rings Chemical Compatibility chart.  

Fluorosilicone O-rings are ideal in static applications, but have poor abrasion resistance due to physical characteristics.
