Our O-ring Materials
We offer O-rings in an extensive range of materials, ensuring you always find the right seal for your specific application, whether it involves extreme temperatures, aggressive chemicals, high pressures, or dynamic conditions:
- NBR (Nitrile Rubber): The most widely used O-ring material, offering excellent resistance to oils, fuels, and hydraulic fluids.
- FKM / FPM (Viton®): High-performance fluorocarbon O-rings with outstanding resistance to heat, chemicals, and fuels.
- EPDM: Ideal for outdoor, steam, and water applications due to excellent weather and ozone resistance.
- Silicone (VMQ/MVQ): Excellent flexibility across a wide temperature range, commonly used in food and medical applications.
- FFKM / FFPM (Perfluoroelastomer): The highest-performing O-ring material, resistant to virtually all chemicals and extreme temperatures.
- PTFE (Teflon®): Chemically inert with very low friction, suitable for aggressive media and cleanroom environments.
- HNBR (Hydrogenated Nitrile): Superior mechanical strength and resistance to ozone, making it ideal for automotive and refrigeration systems.
- FEP Encapsulated O-rings: A chemically resistant FEP outer layer combined with a flexible core, perfect for aggressive chemical environments.
- Polyurethane (AU/PU): High abrasion and wear resistance, widely used in dynamic hydraulic and pneumatic applications.
- FVMQ (Fluorosilicone): Combines the temperature flexibility of silicone with resistance to fuels and oils.
- FEPM (Aflas®): Excellent resistance to steam, amines, and sour gas, used in oil and gas and chemical processing.
- CR (Neoprene): Good general-purpose material with resistance to ozone, weathering, and moderate chemicals.
- ACM (Polyacrylate): Excellent heat and oil resistance, particularly suited for automotive transmission systems.
- ECO (Epichlorohydrin): Good resistance to ozone and moderate fuels, often used in automotive fuel systems.
