FVMQ oil seals

Fluorosilicone / FVMQ

Fluorosilicone (FVMQ) combines the good resistance to high and low-temperatures of silicone with resistance to fuel and oils. The main uses of Fluorosilicone (FVMQ) O-rings are in fuel systems and are ideal for prolonged immersion in fuels, oils, solvents and aggressive fluids.

Recommended for elevated temperatures where the dry-heat resistances of silicone O-rings are required.

Basic Temperature Service Range: -55°C to 205°C

Our standard fluorosilicone (F70) meets the requirements of MIL-R-25988 Class1 Grade 70.

We are also able to supply other fluorosilicone (FVMQ) compounds, many of which meet Aerospace specifications.

exhibit improved resistance to compression set. Many fluorosilicone compounds have a higher than normal shrinkage rate so production molds for fluorosilicone products are often different from molds for nitrile.
