Eco friendly in stock AS568 RoHS Fluorocarbon FKM O ring


O-ring is a kind of rubber ring whose cross-section shape is round, which is most widely used in the hydraulic, pneumatic system.It has good sealing performance, which can be used for both static and dynamic sealing. Not only can it be used alone, but it is also a fundamental component of many combined sealing devices. It has a wide range of applications, and if the materials are selected properly, it can meet the requirements of various media and motion conditions.

Product features: 

1. Suit for many kinds of seal form: Static sealing, dynamic sealing.
2. Suit for many kinds of activity mode: Rotary motion, axial reciprocating motion, or combined motion (such as rotary reciprocating combined motion).
3. Suit for many different sealing media: Oil, water, gas, chemical medium or other mixed medium.
4. Simple design, compact structure, convenient assembly and disassembly.
5. Small running friction.

The O-ring seal is suitable for installation on various mechanical equipment, serving as a seal under specified temperature, pressure, and different liquid and gas media, whether in a stationary or moving state. Various types of sealing components are widely used in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and various instruments and meters.

The O-ring is mainly used for static sealing and reciprocating motion sealing. When used for rotary motion sealing, it is only limited to low-speed rotary sealing devices. It is generally installed in a groove with a rectangular cross-section on the outer or inner circle to serve as a seal.

The O-ring still plays a good sealing and shock absorption role in environments such as oil resistance, acid and alkali resistance, abrasion, and chemical erosion.Therefore, the O-ring is the most widely used seal in hydraulic and pneumatic transmission systems.

The O-ring has its own sealing function and does not undergo periodic adjustments. When used for sliding sealing, the sealing performance is not affected by the direction of movement, and it is small in size and convenient to use. Due to its adaptability, the sealing ring has a wide range of applications. However, it is prone to deformation when the pressure peak reaches a certain pressure, and there is a possibility of squeezing out gaps. It is widely used in aviation and hydraulic engineering
