The o-ring cord series is a range of extruded elastomeric cords with a circular cross-section, commonly used to create custom-sized o-rings. O-ring cords are available in various diameters and materials to adapt to diverse operating conditions—whether it’s pressure, temperature, or fluid compatibility.
Material Versatility for Demanding Applications
DEDE is O-ring cord series covers a wide selection of materials, each offering unique performance traits:
· Nitrile (NBR): Known for excellent oil and fuel resistance, ideal for general industrial machinery and automotive systems.
· Fluororubber (FKM): Delivers outstanding high-temperature and chemical resistance, making it suitable for chemically aggressive environments and high-performance engines.
Standard cross-sectional diameters range from 1 mm to 20 mm, while the cord length can be customized to suit your design requirements. In practical use, these cords are often cut and bonded—sometimes vulcanized—into closed-loop O-rings, suitable for square grooves or face-sealing structures.
