Designed for emergency alternative to molded curved radiator hose. Precision molded in standard lengths, Dayco's Flex Radiator Hose is designed to replace straight or molded radiator hoses. The knitted reinforcement and synthetic EPDM construction meets SAE J20R4, Class D-2 requirements, preventing splitting, ballooning, and elongation, and resisting ozone and other detrimental environmental elements, coolants, and temperature variations of -40°F (-40°C) to +257°F (+125°C). The corrugations, combined with the inserted helical steel coil spring, provide excellent hose flexibility without flattening or collapse. Dayco's Flex Radiator Hose has a convenient plastic hang strap attached for quick and easy merchandising. Note: NOT suitable for fuel or oil transfer.
