FLUOROSILICONE O RINGS

Fluorosilicone rubber contains trifluoropropyl groups next to the methyl groups. The mechanical and physical properties are very similar to silicone rubber. However, fluorosilicone offers improved fuel and mineral oil resistance but poor hot air resistance when compared with silicone.

Both o-rings and gaskets can be made from Fluorosilicone materials.
