Fluorosilicone Oring
FVMQ
Shore A Description:
The hardness of rubber compounds is measured by the Shore A durometer; the higher the durometer, the harder the compound. Softer compounds stretch easier and seal better on rough surfaces. Harder compounds offer greater abrasion resistance and resistance to extrusion.
60 Shore A is softer than 70
70 Shore A is the standard
90 Short A is very stiff
Specs:
Good low/high temperature resistance with excellent resistance to petroleum oils and fuels.
Material:
FVMQ (Fluorosilicon)
Standard Service Temperature: -80°F - +350°F/400°F
Application:
Petroleum Oils and Fuels, Dry Heat/Oil
Used in aerospace applications for fuel systems and systems requiring resistance to diester base lubricants to 350°F. Due to limited strength and abrasion resistance they are generally recommended for static applications only.
Not Compatible With: Phosphate Esters, Ketones, Brake Fluids
