## Definition

a thin ring or strip of material that you put between two parts to stop them from leaking. It keeps liquids or gases from escaping where they are joined.

For teachers: a flexible ring or strip of material, such as rubber or metal, used to seal the joint between two surfaces. It prevents the escape of fluids or gases and maintains a tight seal under pressure.

## Examples
