A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression. It is a deformable material that is used to create a static seal and maintain that seal under various operating conditions in a mechanical assembly. [1]
A seal is a device or material that helps join systems, mechanisms or other materials together by preventing leakage (e.g. in a pumping system), containing pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets .
Chemical process and petroleum refining, where they are used for seals, pumps, gaskets and so on, due to their resistance to chemicals; Analysis and process instruments: separators, diaphragms, cylindrical fittings, hoops, gaskets, etc. Semiconductor manufacturing; Food and pharmaceutical, because of their low degradation, also in contact with ...
The growth of the global PTFE market can largely be attributed to the material’s unique properties, which make it indispensable in modern manufacturing. PTFE’s chemical resistance allows it to withstand harsh environments, making it ideal for automotive applications such as gaskets, hoses, and seals.
A bonded seal consists of an outer annular ring of a hard material, typically steel, and an inner annular ring of an elastomeric material that acts as a gasket. It is the compression of the elastomeric part between the faces of the parts on either side of the bonded seal that provides the sealing action.
Typical O-ring and application. An O-ring, also known as a packing or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, forming a seal at the interface.
