426-3951 62.5 mm ID Radiator Hose
Cat® 62.5 mm ID lower radiator hose for connecting the engine outlet to the cooler inlet
Description
The radiator hose is responsible for carrying coolant from the engine to the radiator, where it is cooled before returning to the engine. The upper radiator hose is made of durable, heat-resistant materials such as rubber or silicone. These materials are selected for their ability to withstand high temperatures and the corrosiveness of coolant.
Attributes
- Withstands high pressure without deforming or breaking and provides a leak-free connection
- Hose withstands a vacuum of at least 17 kPa at 110°C
- Built to exact specifications for durability and reliability
Applications
The radiator hose prevents the engine from overheating, ensuring optimal engine performance and a tight seal. It is used to facilitate coolant flow, which absorbs excess heat generated during combustion, thereby maintaining optimal engine temperature.
