3. Disassemble the Cylinder Once the boom cylinder is detached, carefully disassemble it. Remove the end caps, which may require a specific tool or technique depending on your excavator model. Take care not to damage any internal components.

At its core, a cylinder gland seal is designed to ensure that the hydraulic or pneumatic fluid remains contained within the cylinder, preventing leakage that can lead to loss of pressure and efficiency. The seal is typically mounted in a gland, which is part of the cylinder housing. As the piston moves within the cylinder, the gland seal interfaces with its surface, creating a barrier that minimizes fluid escape.

In various mechanical and industrial applications, seals play a crucial role in ensuring the longevity and efficiency of equipment. Among the many types of seals available, dust seals and oil seals are two predominant types that serve critical functions. While they may appear similar at first glance, their purposes, designs, and applications differ significantly. This article aims to explore these differences, helping you understand when and why to use each type.
