What is an o-ring?

An o-ring is a simple and versatile ring-shaped packing or sealing device with a circular cross section (from which the "O" in its name is derived). The purpose of using O-ring seals is to prevent leakage and loss of liquids or gases. They simplicity, convenience, and small installation space. As long as the groove design and material selection are correct, and the operating conditions are within the temperature range of the rubber material, the seal can have a long-term sealing effect in the static or dynamic seal.
The size of o-ring is determined by the inner diameter ID and the wire diameter CS. O-ring size calculation: outer diameter = inner diameter + 2 x wire diameter (OD = ID + 2x CS).

Most mechanical systems require seals. These devices help join mechanisms together by
Preventing leakage and are crucial to the functionality of machinery. A gasket is a type of
Seal that is compressed in the area between two or more surfaces.

O-Rings(also known as packing joints) are donut-shaped gaskets that can be used in static
Or dynamic applicaitons. O-Rings are easily manufactured, inexpensive, and dependable;
Making them one of the most common seals used in machinery across the globe.
