FPM O-Ring 800x10 FKM Viton® Fluorocarbon Seal

Heavy-Duty Sealing for Industrial Applications

FKM (Viton®) Material Performance and Chemical Resistance

Technical Data and Installation Guidelines

Main Description:
The FPM O-Ring 800x10 FKM Viton® is a large-diameter fluorocarbon sealing ring designed for demanding industrial applications requiring exceptional chemical and thermal resistance. With an inner diameter of 800 mm and a cross-section of 10 mm, this O-ring is engineered for static sealing in large housings, flanges, covers and heavy machinery assemblies.

Manufactured from high-performance FPM (FKM, Viton®) elastomer, this technical seal offers outstanding resistance to oils and grease, fuels, hydraulic fluids and many aggressive chemicals. Compared to standard NBR compounds, FKM provides superior performance at elevated temperatures and under long-term exposure to harsh media. This ensures high durability and dimensional stability even in critical operating environments.

The FPM O-ring 800x10 is commonly used in industrial applications such as chemical processing systems, energy installations, large gearboxes and heavy equipment. It can complement components like a rotary shaft seal, oil seal or shaft sealing ring within complex sealing systems. While a rotary shaft seal or double lip oil seal (TC type) is used for dynamic shaft sealing, this O-ring primarily functions as a static seal, ensuring tight flange or housing connections.

Its precision-molded geometry and controlled hardness (typically 70 Shore A unless otherwise specified) guarantee consistent compression and reliable sealing performance. For B2B buyers, this fluorocarbon O-ring represents a long-term sealing solution in hydraulic and automotive seals where high temperature and chemical resistance are essential.

FAQ

1. What is the difference between FKM (FPM) and NBR O-rings?
FKM offers significantly higher temperature and chemical resistance compared to NBR, making it suitable for aggressive media and high-temperature environments.

2. Can this O-ring be used as a rotary shaft seal?
No. An O-ring is mainly used for static sealing. For rotating shafts, a rotary shaft seal or oil seal should be applied.

3. What temperature range can FKM typically withstand?
Depending on the compound, FKM can operate continuously up to around +200°C.

4. How do I select the correct O-ring size?
Match the inner diameter to the groove diameter and ensure the cross-section (10 mm) fits the gland dimensions for proper compression.

5. Is this O-ring suitable for fuel and oil exposure?
Yes. FKM provides excellent resistance to oils, fuels and many industrial chemicals.
