Viton Flange Gaskets
A Viton (FKM) flange gasket is an elastomer gasket made of fluorocarbon rubber with high resistance to oils, fuels, aromatic hydrocarbons and many chemicals. It keeps its rubber elasticity at high temperature too.
A similar manufacturer datasheet gives an operating temperature of −25 °C to +200 °C for FKM seals. It is used on fuel and oil lines, in chemical plants and at joints where EPDM is affected by oil.
Main Applications
- Fuel and fuel oil lines
- Hydraulic and lubricating oil lines
- Chemical process lines
- Compressor and vacuum lines
- High-temperature oil circuits
