DIN3771 Green FKM O-Rings
DIN3771 green FKM O-rings are high-performance sealing components designed for reliable fluid sealing in demanding industrial environments. The DIN3771 green FKM O-rings are manufactured from fluorocarbon rubber (FKM), offering excellent resistance to high temperatures, fuels, oils, chemicals, and aggressive media.
The DIN3771 green FKM O-rings are widely used in hydraulic systems, automotive equipment, aerospace components, chemical processing systems, pumps, valves, and industrial machinery where durable sealing performance and long service life are required.
Product Overview
DIN3771 green FKM O-rings are precision-engineered circular sealing rings used for static and dynamic sealing applications. Their round cross-section creates an effective sealing barrier when compressed between mating components.
FKM material provides outstanding resistance to petroleum-based fluids, lubricants, solvents, and elevated temperatures. The green color helps identify the material type during assembly and maintenance.
Compared with standard rubber sealing products, the DIN3771 green FKM O-rings provide improved chemical stability, temperature resistance, and aging performance. They are suitable for critical applications where conventional elastomers may not provide sufficient durability.
