Telescopic cylinder seal kit for Terex A380

The N40496-45 seal kit consists of a collection of gaskets, wipers, and rings engineered to restore hydraulic containment within telescopic cylinders. These components function by maintaining pressure and preventing fluid bypass, which is necessary for the controlled extension and retraction of the crane boom. By replacing the internal seals, the hydraulic cylinder can maintain the force required for lifting operations.

This kit is compatible with the Terex A380 crane model. It is designed to service the specific telescopic cylinder assembly used in this machine, ensuring that the hydraulic system operates within its intended parameters. Each seal within the kit is sized to match the internal dimensions of the cylinder, providing the necessary barrier between the hydraulic fluid and the external environment.

Seal kits are used in hydraulic systems to manage the interface between moving parts, such as the piston and the cylinder bore, or the rod and the cylinder head. Over time, these seals can experience wear due to friction and pressure cycles, which may lead to fluid leaks or a loss of hydraulic efficiency. Regular maintenance involving the replacement of these seals helps preserve the operational integrity of the hydraulic system.
