Detailed Description

The 707-99-66600 SEAL KIT HYDRAULIC CYLINDER KOMATSU is the heart of any reliable hydraulic rebuild for Komatsu equipment. Composed of several dynamic and static seals, this kit is designed to withstand aggressive environments, high hydraulic pressures, and the demanding workload expected of Komatsu machines in construction, mining, demolition, and forestry.

Each seal in the kit has a specialized role: the rod seal prevents fluid from escaping the cylinder through the rod, while the piston seal manages pressure buildup on both sides of the piston for smooth operation. Wiper seals ensure that debris, water, and dust don’t contaminate the system, extending the lifespan of internal components. Backup rings add support and resist extrusion, ensuring all other seals stay firmly seated under extreme conditions.

Unlike off-spec alternatives, the 707-99-66600 SEAL KIT HYDRAULIC CYLINDER KOMATSU is manufactured to tight tolerances, ensuring a perfect fit, easier installation, and longer service life. It’s ideal for both OEM cylinder servicing and aftermarket repairs.
