O-Ring FPM 210x5.3 - Fluorocarbon FKM Sealing Ring

High-resistance FKM O-ring for demanding industrial applications

Reliable static and selected dynamic sealing

Main product description

The O-ring FPM 210x5.3 is a high-performance industrial sealing ring manufactured from fluorocarbon elastomer FKM, also known as FPM, Viton or fluor rubber. On the Polish and European markets, this product is commonly searched under terms such as “O-ring FPM 210x5.3”, “FKM O-ring”, “Viton O-ring” and “fluorocarbon sealing ring”, reflecting its use in professional industrial environments.

FKM material is valued for its exceptional resistance to oils, fuels, greases, chemicals and aggressive media, as well as its ability to operate reliably at elevated temperatures. Compared to standard rubber materials, fluorocarbon elastomers provide superior dimensional stability, reduced aging and long-term sealing performance in demanding conditions.

With an internal diameter of 210 mm and a 5.3 mm cross-section, this O-ring ensures uniform compression around the entire circumference. This design supports effective static sealing and allows use in selected dynamic applications, depending on operating parameters such as pressure, speed and lubrication.

The O-ring FPM 210x5.3 is widely used in industrial applications, including hydraulic and pneumatic systems, chemical processing equipment, machinery, energy installations and technical assemblies where standard elastomer seals may fail. Its predictable behavior and high resistance help reduce downtime and improve system reliability.

For B2B customers, this fluorocarbon O-ring represents a dependable technical sealing solution where safety, durability and resistance to harsh operating conditions are essential.
