O-Ring FPM 25x2,65 FKM Viton - High Temperature Seal

FKM Viton O-Ring for Demanding Industrial Sealing

High Chemical and Thermal Resistance

Technical Data and Industrial Applications

Main Description:
The O-Ring FPM 25x2,65 made from FKM (Viton, fluorocarbon rubber) is a high-performance industrial sealing component designed for aggressive chemical environments and elevated temperatures. With an inner diameter of 25 mm and a cross-section of 2,65 mm, this precision rubber seal is widely used in hydraulic systems, pneumatic installations, pumps, valves and industrial machinery.

FKM material, commonly known under the trade name Viton, is globally recognized for its outstanding chemical resistance, high durability and long service life. Compared to standard NBR compounds, FPM offers superior resistance to oils, fuels, hydraulic fluids, lubricants and many aggressive chemicals. It also maintains elasticity and sealing integrity at high operating temperatures, making it suitable for demanding industrial sealing applications.

This O-Ring functions as a static seal or moderate dynamic sealing ring in mechanical assemblies where leak prevention is critical. It is commonly installed as a rubber gasket in grooves designed according to international sealing standards. The 70 Shore A hardness ensures proper compression set behavior, stable contact pressure and reliable sealing performance over extended operating cycles.

Engineers and procurement managers choose FKM O-Rings for hydraulic and pneumatic applications where resistance to oils and heat is essential. The O-Ring FPM 25x2,65 supports high durability, dimensional stability and predictable sealing performance in industrial environments, chemical processing systems and automotive components.
