O-Ring for installation in a wide variety of machinery and equipment, at the specified temperature, pressure, and various liquids and gases, in the stationary or moving under the seal. In machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, as well as various types of instrumentation, the large number of applications using different types of sealing components. O-ring is mainly used for static seals and reciprocating seals. Seal for rotary motion, is limited to low-speed rotary sealing device. Ring is usually installed on the inner circle in the cylindrical or rectangular cross-section of the groove of seal. O ring in oil, acid, grinding, chemical erosion and other environmental still play good sealing, damping. Therefore, O-ring hydraulic and pneumatic drive system most widely used as a seal.
HNBR O ring meets higher temperatures than standard NBR
Offers several advantages over standard NBR O rings, including higher temperature resistance, oil resistance, and a wider temperature range. These characteristics make them suitable for use in challenging environments, from which they stand out. In addition, they provide consistent sealing performance in a variety of industries including automotive, oil and gas, and manufacturing because they are hydrated to improve their physical properties, temperature resistance, and chemical compatibility. HNBR seals provide a reliable and efficient solution for aggressive sealing applications.
HNBR O ring has excellent resistance to oils and chemicals
HNBR O-rings are a versatile sealing solution that fills the performance gap between other elastomers. It provides superior oil and chemical resistance for demanding applications in the automotive, industrial, and oil and gas industries. The hydrogenated structure of HNBR O-rings enables them to perform well at higher temperatures than NBR, making them suitable for use in high-temperature applications where standard NBR may not be able to withstand the heat or aggressive substances. These unique properties make HNBR seals a valuable choice for demanding applications where reliable sealing performance is essential.
