O-ring for Putzmeister machinery

The O-ring 043520000 serves as a sealing component within Putzmeister machinery. It functions as a toroidal gasket to create a seal between two mating parts, preventing the loss of hydraulic fluid and the ingress of external contaminants into the system. This component is used across various hydraulic assemblies, including cylinders, valves, pumps, and fluid connections, to maintain system integrity under operational pressures.

This part is compatible with a wide range of Putzmeister equipment, including concrete pumps, distribution booms, and tunneling machinery. It is designed to fit into standard grooves where a static or dynamic seal is required to contain pressurized fluids. Proper installation of this seal is necessary to maintain the pressure levels required for the movement and force of hydraulic actuators.

O-rings act as the primary barrier against leaks in hydraulic and pneumatic circuits. When compressed within a housing, the material deforms to fill the gap between surfaces, creating a seal that blocks fluid paths. Regular inspection and replacement of these seals are standard maintenance procedures to prevent pressure drops and fluid loss in heavy machinery systems.
