Detailed Product Description

The Gates Molded Coolant Hose 21468 is designed to meet the demanding requirements of radiator coolant systems. Made from EPDM, a synthetic rubber known for its resistance to heat, ozone, and automotive fluids, this hose maintains flexibility and durability under high-temperature conditions. The molded construction ensures a precise shape that fits specific radiator connections, reducing the risk of leaks and hose failure. The internal spring reinforcement helps the hose maintain its form and prevents collapse under vacuum or pressure fluctuations.

This hose features two different inside diameters at each end—2 inches (51 mm) on one side and 2.38 inches (60 mm) on the other—allowing it to connect components with varying sizes. With a centerline length of 21.6 inches (549 mm), it is suitable for applications requiring this specific length and diameter combination. The absence of quick connect fittings and branches indicates a straightforward installation focused on durability and reliability.
