FKM O-Rings (Viton® O-Rings)

FKM (fluorocarbon rubber), commonly known by the trademark Viton®, is a high-performance elastomer selected for its exceptional resistance to heat, oils, fuels, and a wide range of aggressive chemicals. FKM O-rings maintain their sealing integrity under prolonged exposure to harsh environments where standard elastomers would degrade.

These seals are engineered for stability in critical applications across automotive, chemical processing, oil & gas, and industrial hydraulic systems. Their low compression set and excellent aging resistance ensure consistent performance over extended service life, reducing maintenance frequency and system downtime.

Key Features

• Excellent resistance to high temperatures up to +200°C

• Superior chemical resistance to oils, fuels, and many aggressive media

• Low compression set for sustained sealing force over time

• Good resistance to aging, ozone, and weathering

• Stable mechanical properties in demanding operating conditions

Applications

• Automotive engines and fuel injection systems

• Chemical processing pumps, valves, and reactors

• Oil & gas extraction and refining equipment

• Industrial hydraulic and pneumatic systems

• Aerospace and semiconductor manufacturing tools

Material Advantages

Compared with NBR or EPDM, FKM offers significantly better resistance to heat, oils, fuels, and aggressive chemicals. While it has limited low-temperature flexibility, its stability under long-term high-temperature exposure makes it the preferred choice for critical sealing applications in harsh environments.
