O-Ring FPM 620x10 FKM - Large Diameter High Temp Seal

Large Diameter FKM O-Ring for Industrial Sealing

High Chemical Resistance and Thermal Stability

Applications in Heavy Industry and Hydraulic Systems

Main Description:
The O-Ring FPM 620x10 is a large-diameter industrial sealing ring manufactured from fluorocarbon rubber FKM (also known as Viton or Fluor). Designed for demanding environments, this rubber gasket provides outstanding resistance to high temperatures, aggressive chemicals, fuels, synthetic oils and industrial lubricants.

With an inner diameter of 620 mm and a cross-section of 10 mm, this O-Ring is engineered for large flanges, tank covers, heavy machinery housings and hydraulic systems requiring secure static sealing. The FPM compound ensures long-term dimensional stability and high durability even at temperatures reaching approximately +200°C, depending on operating conditions.

Compared to standard NBR rubber seals, FKM offers significantly improved chemical resistance and heat stability. This makes the O-Ring 620x10 particularly suitable for heavy-duty industrial applications where reliability and safety are critical. It performs effectively as a static seal in pressure-loaded assemblies and maintains sealing integrity under thermal expansion and mechanical stress.

The precision-molded profile guarantees uniform compression within the groove, creating a reliable industrial sealing solution that minimizes leakage risk. This technical sealing component is commonly used in chemical processing plants, energy production systems, hydraulic and pneumatic applications, and large-scale industrial equipment.

For engineers, procurement managers and maintenance teams, the O-Ring FPM 620x10 provides a dependable high-performance sealing solution designed for extended service life and reduced downtime in critical installations.
