China HITACHI EX300-2-3 BOOM RAM SEAL KIT (OEM HI 9078845) | Tonkee®

The boom cylinder is a vital hydraulic component of an excavator, responsible for extending and retracting the boom arm, which is used for various excavation and material handling tasks.

To prevent hydraulic fluid leaks and maintain the cylinder's functionality, a high-quality seal kit is essential.

The OEM designation "HI 9078845" signifies that this seal kit is manufactured by Hitachi itself, ensuring compatibility and performance in Hitachi EX300-2 and EX300-3 excavators. OEM parts are known for their quality and reliability, making them the preferred choice for equipment maintenance and repair.

The seal kit consists of several key components, including seals, o-rings, and gaskets. These components are made from durable materials that can withstand the high pressures and harsh conditions within the hydraulic system. They are designed to create a secure seal between moving parts of the boom cylinder, preventing hydraulic fluid from escaping and contaminants from entering the system.

Proper installation of the seal kit is crucial to maintaining the excavator's hydraulic efficiency.

When installed correctly, it helps prevent issues such as fluid leakage, which can lead to reduced performance, increased operating costs, and potential damage to other hydraulic components.

Routine maintenance and replacement of seal kits are essential to ensure the longevity and optimal performance of the excavator. Over time, seals can wear out due to the constant movement and pressure within the hydraulic system. Regular inspection and replacement of seal kits when necessary can prevent costly downtime and repairs.
