Heavy-Duty Boom Cylinder Seal Kits: Prevent Leaks & Restore Lifting Power

Is your excavator's boom drifting or showing visible oil leaks? A worn boom cylinder seal kit is often the cause of hydraulic pressure loss, which directly affects your machine’s lifting capacity and precision. To maintain peak performance, timely replacement of these seals is essential. BeeSpareParts offers high-quality aftermarket boom cylinder seal kits designed to withstand the extreme pressures and shock loads of heavy-duty excavation.

Our compatible seal solutions are manufactured using premium materials like high-temperature Nitrile (NBR) and wear-resistant Polyurethane (PU). Each kit is a complete repair solution, providing a direct fit for Caterpillar (CAT), Komatsu, and Volvo equipment. These kits include all necessary rod seals, piston seals, wipers, and O-rings to ensure a professional, leak-proof rebuild that meets or exceeds OEM standards.

Key Performance Benefits:

Stop Boom Drift: High-performance piston seals maintain internal pressure to prevent the boom from sinking under load.
Extreme Durability: Engineered to resist abrasion and heat in harsh environments like mining and construction sites.
Precise Compatibility: Tailored kits designed to fit for CAT, Komatsu, Volvo, and Hitachi models, ensuring a hassle-free installation.
