An O-ring is a mechanical gasket in the shape of a torus, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface. It works by blocking the pathway that a fluid or gas may escape through, and the pressure applied either by hydraulic or pneumatic pressure actually enhances the sealing function. References: 1. "What is an O-Ring? Introduction to O-Rings" from the website of Gallagher Fluid Seals (https://www.gallagherseals.com/blog/w...). The explanation can be found in the first and second paragraphs of the article. 2. "O-ring" from Wikipedia (https://en.wikipedia.org/wiki/O-ring). The functioning of an O-ring is explained in the first paragraph under the "Function" section.
