Refers to O-ring seals that comply with international standards or industry norms.

However, generally speaking, an O-ring is a rubber sealing ring with a circular cross-section, named after its O-shaped cross-section. It is the most common mechanical design for sealing, characterized by small size, easy assembly and disassembly, both dynamic and static seals available, almost no leakage of static seals, single piece use of bidirectional seals, low dynamic friction, and low price.

O-ring seals are widely used for sealing various mechanical equipment, such as 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. In these application fields, it is widely used as a static and reciprocating sealing element, as well as a rotary sealing element, but only limited to low-speed rotary sealing devices.

When installing and using O-ring seals, it is necessary to pay attention to the force generated by the system pressure acting on the O-ring seal and the initial compression amount of the O-ring seal in the radial or axial direction during installation. These two factors will directly affect the initial sealing ability of the O-ring. Only when the initial deformation and stress of the sealing element, Pw>Pseal, can absolute sealing without leakage be achieved.

In short, O-ring seals are a common and reliable sealing element, which are widely used and have multiple excellent characteristics. If you need more specific information, it is recommended to refer to the official channels of the relevant products or contact professionals for consultation.
