A fixed seal used to prevent leakage by clamping it between contact surfaces that do not move relative to one another (→ packing). Materials used are not affected by the fluid in the container or pipe, and do not lose elasticity under pressure or temperature. Currently, there are three types: (1) Nonmetallic gaskets Made of leather, asbestos, rubber, synthetic resin, etc., and available in flat, square, round (O-ring), V-shaped, etc. (2) Semi-metallic gaskets Made of rubber and asbestos containing metal, or a combination of metal and asbestos, and available in parallel, corrugated, sawtooth, and spiral types. (3) Metallic gaskets Made of aluminum, brass, monet metal, lead, iron, or other metal materials, and used for high temperatures and high pressures.
