Detailed Product Description

This radiator coolant hose is made from EPDM, a synthetic rubber known for its excellent resistance to heat, ozone, and coolant chemicals.

The hose measures 12.595 inches (320 mm) in centerline length, matching OEM specifications for a proper fit. The molded construction means the hose is shaped to fit the exact routing required by the vehicle, which helps maintain coolant flow and prevents kinks or stress points. This hose does not include springs or quick connect fittings, making it suitable for applications that require a straightforward, molded replacement.
