O-ring

An O-ring is a small, circular sealing device made of flexible material like rubber. Its primary purpose is to prevent leaks by filling the space between two parts, such as pipes or machinery components, ensuring a tight seal. When the parts are assembled and pressure is applied, the O-ring compresses slightly, blocking liquids or gases from escaping. O-rings are widely used in industries like plumbing, automotive, and aerospace due to their reliability and simplicity in creating effective seals in various mechanical systems.
