O-Ring is a rubber sealing ring with a circular cross-section, and is called an O-ring rubber sealing ring because of its O-shaped cross-section.
Due to its simple manufacturing, affordable price, reliable functionality, and simple installation requirements, O-ring is the most common sealing product. O-rings can withstand pressures of tens of megapascals. It is mainly used for static sealing and reciprocating sealing.
