Cooling System Water Hose-421-03-22111

Product Advantages

High Original Equipment Compatibility: Manufactured strictly according to Komatsu's original technical specifications, with dimensions and interfaces precisely adapted to D65/D85 models. No additional modifications are required, ensuring perfect compatibility with the entire system after installation, reducing compatibility risks.

High Durability: Utilizes a three-layer composite structure. The inner layer is made of high-temperature resistant EPDM rubber, resistant to coolant corrosion and withstanding temperatures up to 135℃. The middle layer is a high-strength polyester fiber woven mesh, capable of withstanding 0.5MPa system working pressure without the risk of expansion or bursting. The outer layer is made of wear-resistant neoprene rubber, resistant to aging and wear, extending service life.

Good Adaptability to Operating Conditions: Wide operating temperature range, capable of handling extreme environments from -30℃ to 135℃, suitable for high and low temperature operating scenarios; excellent flexibility facilitates installation and maintenance, while also absorbing engine and chassis vibrations, reducing pipeline fatigue damage.

Low Maintenance Costs: Long service life reduces the frequency of replacements; strong adaptability and simplified procurement and replacement processes reduce downtime and maintenance costs.

Applicable Scenarios

Suitable for heavy-duty operations of Komatsu D65/D85 bulldozers in mining stripping, road construction, land leveling, water conservancy projects, etc., especially suitable for long-term continuous operation. It is a key wear part to ensure stable operation of the equipment.
