DaycoŽ Small I.D. Molded Heater Hose is designed to replace OEM coolant hose in applications where molded hose in small diameters (1" I.D. or smaller) is required.

• The molded configuration eliminates the need for multiple connections of hoses and clamps.
• The knitted reinforcement and synthetic EPDM construction provides high strength and resistance to detrimental environmental elements, coolants, and temperature variations of -40°F (-40°C) to +257°F (+125°C).
• If the OE parts have a "quick connect" end, the DaycoŽ Small I.D. Molded Heater Hoses are also made with the quick connect assembled onto the hose for fast, convenient installation.
• Meets SAE J20R4 EC, Class D-1 requirements
