FVMQ Rubber O Ring Seals

General Description

Fluorosilicone is a widely used elastomer that can be compounded to meet a wide range of applications.  The mechanical and physical properties are very similar to silicone rubber. However, fluorosilicone offers improved fuels and mineral oil resistance but poor hot air resistance when compared with silicone. This material is widely used in semiconductor Ashing equipment for its resistance to oxygen plasma.

Common Names

Fluorosilicone o ring, FVMQ o ring

Features

1. Use where excellent fluid resistance is needed at extreme low temperature

Applications

1. Fuel injectors
2. Quick connects
3. Fuel pumps
4. Fuel tank seals
5. Any seal application dealing with fuels at low temperatures

Limitations

Due to limited physical strength, poor abrasion resistance, and high friction characteristics, Fluorosilicone elastomers are not generally recommended for dynamic sealing. They are predominately designed for static sealing use. They are also not recommended for exposure to brake fluids, hydrazine, or ketones.
