Static Seals: page 25
Static seals are sealing elements used in fixed joints in hydraulic, pneumatic and mechanical systems: flanges, covers, fittings and other connections where there is no relative movement between components. Their role is to prevent fluid leakage through the joint, maintaining the pressure and integrity of the system. Unlike dynamic seals, static seals are not subject to wear caused by friction, but must withstand working pressures and the chemical aggressiveness of the fluid. In the Hydraulic Seals Store catalogue, you will find static seals made from NBR rubber, FKM and other materials, available from stock with fast delivery in Romania.
The role of static seals in sealing fixed components
Static seals are compressed between two fixed surfaces, creating a leak-proof barrier against fluid leakage. They are used in all types of hydraulic and pneumatic systems, whether in the assembly of cylinders or in the connection of pipes and valves.
Where are static seals used?
- the flanges of hydraulic cylinders and pumps;
- covers and connections on hydraulic valves;
- joints in hydraulic pipes and fittings;
- industrial pneumatic systems;
- heat exchangers and process equipment.

What are the key characteristics of static seals?
Pressure resistance, fluid compatibility and dimensional stability
Static seals must withstand the system’s working pressure without extruding or becoming permanently deformed. The material must be chemically compatible with the fluid used (mineral oil, synthetic fluid, water or chemicals). Dimensional stability ensures that the seal remains effective throughout the seals’ service life. NBR rubber is suitable for mineral oil-based fluids, whilst FKM withstands aggressive fluids and high temperatures.

Frequently Asked Questions
What are static seals?
Static seals are sealing elements used in fixed joints in hydraulic and pneumatic systems. They are compressed between two fixed surfaces to prevent fluid leaks.
Where are static seals used?
Static seals are used in hydraulic cylinder flanges, pump covers, valve connections, pipe joints and in any fixed connection within hydraulic or pneumatic systems.
What materials are recommended for static seals?
NBR, EPDM, silicone, PTFE, graphite and metallic materials are frequently used for static seals, depending on the operating conditions.
How do static seals prevent leaks?
Static seals prevent leaks by compressing between two fixed surfaces, filling the gaps and ensuring a seal.
