PISTON SEAL
Piston Seals or Piston Rings are used in hydraulic cylinders for fluid sealing. They are internal to the cylinder head and seal against the cylinder bore, preventing fluid from flowing across the cylinder head. This allows pressure build up on one side of the piston, making the cylinder extend or retract. piston seals can cover working temperatures from -50°C to 230°C and working pressures up to 800 bar. Some seal profiles are insensitive to extreme pressure peaks.
