Dayco 81311 Flex Radiator Hose 1.75" x 11.25" EPDM Rubber

The Dayco 81311 flexible radiator hose is engineered to replace straight or molded radiator hoses on a wide range of automotive applications. This precision-corrugated hose features knitted reinforcement and synthetic EPDM construction combined with an inserted helical steel coil spring, providing superior flexibility and durability in demanding cooling system environments.

Key Features:

• 1.75-inch inner diameter with 11.25-inch length for universal fitment
• Resists ozone and other detrimental environmental elements, coolants and temperature variations of -40°F (-40°C) to +257°F (+125°C)
• Excellent flexibility without flattening or collapsing, as well as the ability to resist splitting, ballooning, and elongation
• Helical steel coil spring insert for increased flexibility and collapse resistance
• Single inner diameter design for simplified installation
• Black EPDM rubber construction for long service life

This flex hose provides a reliable, cost-effective solution for cooling system repairs and custom installations where flexible routing is required. The corrugated design allows the hose to bend and conform to tight spaces while maintaining consistent coolant flow without kinking or restricting passage.
