Detailed Product Description

The Dayco Curved Radiator Hose 72727 is a dual inside diameter hose made from EPDM, a synthetic rubber known for its excellent resistance to heat, ozone, and coolant chemicals. This hose features two different inside diameters—1 1/2 inch on one end and 1 13/16 inch on the other—allowing it to connect components with varying sizes in the cooling system. The outside diameters measure 1 7/8 inch and 2 9/32 inch respectively, ensuring a secure fit with clamps. The hose does not include a heat shield or protective sleeve, which is typical for this type of radiator coolant hose. It meets SAE J20R4 Class D-1 and SAE J1684 Type EC standards, confirming its suitability for automotive coolant applications. The 21 1/2 inch trunk height supports proper installation and routing within the engine bay.
