What is the function of the O-ring?

O-rings are often used in industrial and mechanical equipment to prevent fluid or gas leakage. It is composed of a circular rubber ring with a round cross-section. The O-ring is usually used to connect two parts. One part has a groove in which the O-ring can be installed, and the other part compresses the O-ring to create a tight seal.
The O-ring is usually made of fluorine rubber, silicone rubber, butadiene rubber and other materials, and has high temperature resistance, low temperature resistance, oil resistance, acid and alkali resistance and other properties. This makes them widely used in many industrial and mechanical equipment, such as automobiles, ships, aerospace, oil industries, etc. In these fields, O-rings are often used to seal components such as pipelines, valves, oil seals and pump bodies.
When using the O-ring, you must make sure that the installation position is clean and there is no debris or dirt. Stretch the O-ring slightly and place it in the groove to ensure that the O-ring is installed correctly and not twisted or squeezed. Assemble two parts and compress the O-ring between them to create a tight seal.
In short, the O-ring is an important mechanical seal, which can play a sealing and leakage prevention role in various industries and mechanical equipment. Proper installation and maintenance of the O-ring will help ensure the reliability and long-term use of the equipment.
