Packing is a compressible and resilient material used as a seal on moving parts. Gaskets are used wherever two stationary pieces of metal are brought together in equipment handling liquids or gases. Gaskets are also termed stationary or static seals.
The most common use of gaskets is in the joining of flanges on pipe lines or valves. Seals and gaskets are identified basically by the method of application or type of construction;
These products were used on pipes and boilers and in between joints on ships. When used in between pipe joints as a gasket, sheet packing prevents the contents of the pipe from leaking out.
