What are O-Rings?

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.
