O-rings

Rubber O-ring is a circular rubber ring with a circular cross-section, mainly used for mechanical components to prevent leakage of liquid and gas media under static conditions. In some cases, it can also be used as a dynamic sealing element for axial reciprocating motion and low-speed rotational motion. According to different conditions, different materials can be selected to adapt to it When selecting O-ring, it is usually advisable to choose a large cross-section O-ring. In the same gap, the volume of O-ring squeezed into the gap should be less than the maximum allowable value. For different types of fixed or dynamic sealing applications, O-ring rubber rings provide designers with an effective and economical sealing element. O-ring is a bidirectional sealing element. The initial compression in the radial or axial direction during installation endows the O-ring with its own initial sealing ability. The sealing force generated by system pressure and the initial sealing force combine to form the total sealing force, which increases with the increase of system pressure. The O-ring plays a prominent role in static sealing situations. However, in dynamic and appropriate situations, O-rings are often used, but they are limited by the speed and pressure at the sealing point.
