SPGW
Piston Seal
Advantages and Characteristics
SPGW consists of four components, is made from three materials, and is suitable for bidirectional piston seals with long strokes, high pressure, and heavy loads.
Due to its unique structure, consisting of a combination of three materials, it is particularly suitable for high-speed, long-stroke, heavy-duty hydraulic cylinders, such as excavators, cranes, concrete pump trucks, and missile launchers.
