O-ring for Putzmeister machinery

This O-ring, identified by part number 041321007, serves as a sealing element within the hydraulic and pumping systems of Putzmeister machinery. Its primary function is to establish a hermetic seal between two mating surfaces, effectively preventing fluid leakage and the ingress of external contaminants into the system. The component is manufactured from NBR 90 Shore A material and adheres to the DIN 3771 standard, with specific dimensions of 110 mm inner diameter and a 5 mm cross-section.

This seal is suitable for integration into various hydraulic circuits, including pump cylinders, distribution valves, and pipeline connections found in concrete pumping equipment. The NBR 90 specification indicates the material hardness and chemical compatibility required for these applications. By maintaining a precise fit, this O-ring helps preserve the integrity of the hydraulic circuit, which is necessary for the consistent operation of heavy-duty pumping equipment.

O-rings are used throughout industrial machinery to seal static or dynamic joints. They function by deforming under pressure to fill the gap between components, thereby blocking the path of pressurized fluids. Proper selection based on size and material hardness is essential for maintaining pressure levels and preventing fluid loss in hydraulic assemblies.
