Link-Belt
O-ring for Link-Belt LS-98
This O-ring is designed for use in the hydraulic systems of Link-Belt LS-98, LS418, LS418A, and LS98PL cranes. It serves as a mechanical seal to prevent fluid leakage at connection points.

The AC 1474 O-ring acts as a mechanical sealing component within the hydraulic circuits of Link-Belt machinery. Its primary function is to establish a secure, leak-proof seal between two mating surfaces, such as those found in hydraulic valves, pump housings, and hose fittings. By deforming under compression, the component fills the clearance gap to block the passage of hydraulic fluid, ensuring the system maintains its required operating pressure during lifting and construction tasks.
This component is compatible with several Link-Belt crane models, including the LS-98, LS418, LS418A, and LS98PL. It is intended for integration into systems where maintaining hydraulic integrity is necessary for the consistent operation of cylinders and other actuators. Proper installation ensures that fluid remains contained within the circuit, preventing pressure drops that could otherwise lead to erratic equipment performance or the need for frequent fluid replenishment.
In heavy machinery, O-rings function as the primary barrier against leaks in both hydraulic and pneumatic systems. They are installed in grooves to provide a static or dynamic seal, depending on the specific application within the machine architecture. Regular inspection and replacement of these seals help maintain the overall efficiency of the hydraulic system by preventing external leaks that can compromise machine operation.
