Advanced Seal Package: Caterpillar employs a sophisticated sealing system specifically designed for high-pressure, high-load applications. This includes:
Heavy-Duty Rod Seal: The primary seal is designed to contain extreme internal pressure without leaking, ensuring the boom does not drift down under load—a critical safety and performance feature.
Buffer Seal: Protects the primary seal from pressure spikes, extending its service life.
Robust Wiper Seal: Keeps abrasive contaminants out of the cylinder assembly, protecting the rod surface and internal components from damage.
