Boss plug for Terex RT780

The 216210 boss plug is a hydraulic fitting designed to seal ports within the fluid power circuits of the Terex RT780 crane. It utilizes a 3/4-16 SAE thread configuration to ensure a precise fit into standard hydraulic ports, effectively closing off unused openings or terminating lines to maintain system pressure and prevent fluid loss. This component is engineered to integrate into the machine's hydraulic network, which manages critical functions including boom elevation, outrigger deployment, and slewing operations.

This specific part is compatible with the Terex RT780 model. The design incorporates a tapered seat and O-ring interface consistent with SAE standards for hydraulic connections, ensuring compatibility with other hydraulic components within the assembly. By providing a secure, leak-free seal, this plug helps maintain the integrity of the hydraulic system under the operating pressures typically encountered in heavy lifting equipment.

Hydraulic plugs are essential components in fluid power systems, serving to seal off ports in manifolds, pumps, valves, and cylinders. They prevent the ingress of contaminants and the escape of hydraulic fluid, which is necessary for the consistent performance of crane control systems. Proper installation of these fittings ensures that the hydraulic circuit remains closed and pressurized during operation.
