May 21,2026
O-rings, as small, simple, and easy-to-disassemble sealing rings, have their own advantages, resulting in a wide range of applications. Many industries use O-rings.
Simply put, O-rings are typically installed in rectangular grooves on the outer or inner diameter of a machine to provide a seal. O-rings maintain good sealing and vibration damping properties even in environments resistant to oil, acids, alkalis, abrasion, and chemical corrosion. Various types of sealing elements are widely used in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastics machinery, agricultural machinery, and various instruments and meters.
Among sealing elements, O-rings are an important type. Although we don't see them often, they are commonly used in various mechanical equipment, and as the above description shows, O-rings are indeed widely used.
