Dayco 72780 Curved Radiator Hose

The Dayco 72780 is a precision-molded curved radiator hose designed to replace OEM radiator hoses in automotive cooling systems. This curved design provides proper routing and fitment for specific vehicle applications where standard straight hoses cannot accommodate engine bay configurations.

Key Features:

• Synthetic EPDM rubber construction for superior heat and chemical resistance
• Knitted rayon reinforcement provides maximum strength and burst resistance
• Withstands extreme temperature variations from -40°F to +257°F (-40°C to +125°C)
• Resists degradation from oil, mud, salt, road debris, ozone, and coolants
• Meets SAE J20R4 Class D-1 requirements for light-duty vehicle applications
• Precision-molded curved design ensures proper fit and unrestricted coolant flow

Engineered as a direct aftermarket replacement, this molded radiator hose delivers reliable performance and long service life in demanding cooling system applications. The EPDM construction and reinforced inner tube work together to prevent splitting, ballooning, and premature failure.
