A Gasket is a flat, non-moving, compressible rubber-like device squeezed between two flat surfaces forming a static seal. Gaskets can be made from homogeneous rubber, fabric reinforced rubber, fiberous materials with rubber binders, flexible graphite, PTFE and many other materials.
Some gaskets are made from a combination of metal and fiberous materials and some are all metal. An o-ring, while not flat is also referred to as a gasket at times.
