Aftermarket Adjust Cylinder Seal Kits: Reliable Replacement for Major Excavator Brands

Maintaining proper track tension is vital for undercarriage longevity and machine performance. Our aftermarket adjust cylinder seal kits are high-quality sealing solutions designed to prevent grease leakage and ensure consistent track tension. These kits are engineered as a direct replacement for Caterpillar (CAT), Komatsu, and Hitachi undercarriage systems, offering a cost-effective alternative to original parts without compromising on pressure resistance.

Built for heavy-duty environments, our compatible seal solutions are precision-matched to fit for CAT 320D, Komatsu PC200, and Hitachi ZX210 models. Each kit utilizes premium Polyurethane (PU) and Nitrile (NBR) materials, specifically chosen for their ability to withstand the extreme hydraulic pressures required during track adjustment. Whether you are dealing with sagging tracks or visible grease seepage, our kits provide the reliability needed to keep your machine in operation.

Key Technical Features:

• High-Pressure Integrity: Specifically designed to handle intense grease injection pressures.

• OEM-Spec Compatibility: Engineered as a replacement for top industry brands including Volvo, Doosan, and Kobelco.

• Contamination Protection: Reinforced dust seals and O-rings protect the cylinder from mud, grit, and water.
