O-ring for Konecranes RST-03 SMV 4531

The O-ring 76K242 functions as a sealing element within the hydraulic and pneumatic systems of Konecranes machinery. It creates a seal between two mating surfaces to contain fluids such as hydraulic oil or air and to maintain the required operating pressure within cylinders, valves, pumps, and various system connections. By preventing fluid leakage, this component ensures that the hydraulic energy is transmitted effectively throughout the machine circuits.

This part is compatible with the Konecranes RST-03 SMV 4531 reach stacker. It is designed to fit into specific grooves where the compression of the material provides the necessary seal for the operating environment of this port equipment.

In hydraulic systems, O-rings serve as the primary barrier against leaks in static and dynamic applications. When installed in a groove, the cross-section of the ring is compressed, creating a seal that blocks the path of pressurized fluid. Proper maintenance involves inspecting these seals for signs of wear, such as hardening or cracking, which can lead to pressure loss and system inefficiency. Replacing these components during scheduled maintenance helps maintain the integrity of the hydraulic circuits.
