As a small size, simple structure and easy to disassemble the O-ring, it has its own advantages, so it is widely used in many applications. Many industries use O-rings. The application of the O-ring is simple, and is generally installed in a groove having a rectangular cross section on the outer or inner circumference. O-ring seals still have good sealing and shock absorption in oil, acid, alkali, grinding and chemical corrosion. In the machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and various types of instruments, a large number of types of seals are applied. element. The O-ring seal in the sealing element is an important one. Although we usually see less, it is generally used in some mechanical equipment, and as can be seen from the above range, the O-ring is indeed widely used.
