KL40 is a specialized two-piece double-acting sealing set designed for high-performance hydraulic systems. It consists of a high-hardness polyurethane (PU) seal ring combined with an NBR elastomer ring which functions as the energizer. This combination ensures superior sealing capacity in heavy-duty applications, providing exceptional resistance against wear, pressure, and extrusion.
