Piston seals are mainly used in hydraulic cylinders to seal pressurized fluids between the piston and the bore. They allow radial compression. Its function is to keep the fluids in the chamber so as not to reduce the volumetric efficiency of the pump. This helps ensure optimal performance and maximum system reliability. These gaskets are mainly offered in nitrile (NBR) or polyurethane (PU). Its destination can be hydraulic or pneumatic.
To identify the piston seal necessary for your assembly, you must take these 3 dimensions:
