FPM O-Ring 58x4 FKM/Viton

FPM O-Ring 58x4 - material and properties

The FPM O-Ring 58x4, also known as FKM/Viton, is a high-performance rubber sealing ring designed for demanding industrial environments. Made from fluoroelastomer, it offers outstanding resistance to oils, fuels, hydraulic fluids and aggressive chemicals. This material ensures dimensional stability, elasticity and long service life even under continuous exposure to harsh operating conditions.

With an inner diameter of 58 mm and a cross section of 4 mm, this O-ring is suitable for precision sealing grooves where reliable tightness and durability are critical. It is an industrial sealing solution specifically intended for applications where standard NBR or EPDM O-rings are not sufficient.

Industrial applications

The FPM O-Ring 58x4 FKM is widely used as a sealing ring in hydraulics and pneumatics, as well as in mechanical engineering, chemical processing and energy-related industries. Typical applications include pumps, valves, cylinders, manifolds and housings exposed to elevated temperatures and aggressive media.

Thanks to its high temperature resistance, the O-ring maintains sealing performance over extended operating periods. It is suitable for static sealing and for limited dynamic applications where controlled movement and high reliability are required.

Benefits for B2B customers

For B2B customers, the FPM O-Ring 58x4 provides a dependable technical sealing solution that reduces the risk of leaks, equipment failure and unplanned downtime. The use of FKM material results in longer service intervals, fewer replacements and lower maintenance costs. This makes it a preferred choice for industrial maintenance, production and technical supply operations.

Main product description

The FPM O-Ring 58x4 FKM/Viton is a professional-grade rubber seal designed for high-performance industrial sealing. As a precision-manufactured sealing ring, it offers excellent resistance to heat, chemicals, oils and fuels. The fluoroelastomer compound ensures low compression set, resistance to aging and stable sealing properties throughout its service life.

This O-ring is used as a static seal in flanges and housings, as well as in semi-dynamic applications with moderate movement. Accurate dimensions ensure proper groove fit and uniform compression, delivering reliable sealing performance under pressure and temperature fluctuations.
