O-Ring FPM 290x5.3 - Fluorocarbon FKM Sealing Ring

High-resistance FKM O-ring for industrial applications

Reliable static sealing with optional dynamic use

Main product description

The O-ring FPM 290x5.3 is a high-performance industrial sealing ring manufactured from fluorocarbon elastomer FKM, also known as FPM, Viton or fluor rubber. This type of O-ring is commonly searched under terms such as “O-ring FPM 290x5.3”, “FKM O-ring”, “Viton O-ring” and “fluorocarbon sealing ring”, reflecting its widespread use in professional industrial environments.

Fluorocarbon FKM material is known for its exceptional resistance to oils, fuels, greases, chemicals and aggressive process media, as well as its ability to maintain sealing performance at elevated temperatures. Compared to standard rubber seals, FKM O-rings offer superior aging resistance, dimensional stability and long-term reliability in demanding operating conditions.

With an internal diameter of 290 mm and a 5.3 mm cross-section, this O-ring provides uniform compression around the entire circumference. This geometry supports effective static sealing and allows use in selected dynamic applications, depending on operating speed, pressure and lubrication.

The O-ring FPM 290x5.3 is widely used in industrial applications, including hydraulic and pneumatic systems, chemical processing equipment, machinery, energy installations and process technology systems where conventional elastomer seals may not be sufficient.

For B2B customers, this fluorocarbon O-ring represents a reliable technical sealing solution, helping reduce maintenance frequency, minimize leakage risk and ensure stable operation of industrial systems.
