Galvanized steel connector-421-03-32132

Core Features

Coolant Return: Returns cooled coolant from the radiator to the engine water jacket, completing the cooling cycle and preventing engine overheating.

Pressure Balancing: Maintains stable cooling system pressure, prevents vapor lock, and ensures smooth coolant circulation.

Flexible Connection: Absorbs engine vibration and thermal expansion/contraction displacement (axial compensation ±12 mm), preventing rigid connection breakage.

Leak-Proof Sealing: Sealing lips at both ends + clamps secure the seal, preventing coolant leakage and reducing losses and environmental pollution.

Temperature Resistance and Protection: Suitable for high-temperature and high-pressure operating conditions, resists oil and dust corrosion, and extends service life.

Product Superiority

Original Factory Precise Fit: Length, pipe diameter, and connector angle are perfectly matched to the D65/D85 cooling system, allowing for direct replacement without repair.

High Temperature Resistance and Aging Resistance: The EPDM inner layer is resistant to coolant corrosion over long periods, with no swelling or cracking, and a lifespan of ≥3000 hours.

High Pressure and Explosion Resistance: The steel wire reinforced layer has a burst pressure ≥0.8 MPa, far exceeding the system's working pressure, ensuring a high safety factor.

Durable Sealing: Galvanized steel connectors + dedicated clamps ensure reliable sealing with a leakage rate of <0.05%, suitable for bumpy operations.

Convenient Maintenance: The modular design allows for on-site replacement in just 15-20 minutes, minimizing downtime.

Installation and Maintenance Points

Before installation, inspect the hose for signs of aging, bulging, and cracks. Ensure the connectors are clean and free of rust. Apply coolant to lubricate the sealing lips.

After aligning the connectors, tighten the clamps to a torque of 8-12 N·m. Avoid overtightening to prevent damage to the hose or undertightening to prevent leaks.

Check the clamp tightness and for leaks every 200 hours. Replace the hose every 1500 hours or 1 year to prevent aging and failure.

Avoid contact between the hose and high-temperature components (such as the exhaust manifold). Maintain a distance of ≥50 mm to prevent burns.

Purge air before starting the engine to ensure smooth cooling system circulation and prevent air locks that could cause engine overheating.

Suitable Scenarios and Value

Suitable Scenarios: Suitable for heavy-duty, dusty, and temperature-varying environments such as mines, earthmoving sites, and wetlands, ensuring stable cooling systems.

Core Value: Reduces the risk of engine overheating failures, minimizes downtime losses, and improves overall machine operating efficiency and reliability.
