Fluorosilicone O-Rings 70D (FVMQ) is most often used in aerospace applications for systems requiring fuel and/or diester-based lubricant resistance up to 400° 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.
Metric O-Ring Dimensions are defined by CS Cross Section and ID Inside Diameter. N2.00X012 = 2mm CS X 12mm ID
