Static seals are used to prevent fluid leakage between stationary components in hydraulic and pneumatic systems. Unlike dynamic seals, static seals do not move relative to each other but must resist high pressure and maintain sealing integrity over time.
Backup rings support primary sealing elements like O-rings by preventing their extrusion under pressure. These rings are typically made from hard polymers such as PTFE or nylon, increasing the durability of the sealing system.
Static sealing rings provide tight sealing between fixed parts such as flange connections or valve seats. They can be made from elastomers, plastics, or composites depending on the application requirements.
Key features include high resistance to extrusion and deformation, compatibility with various fluids and temperatures, and precise dimensions to ensure reliable sealing.
