Gates 24879 Premium Molded Heater Hose EPDM 1 Inch Diameter

The Gates 24879 Premium Molded Coolant Hose is a factory-molded heater outlet hose engineered to deliver OEM-quality performance for your vehicle's cooling system. This precision-shaped hose is designed to fit specific applications, ensuring perfectly sealed connections and reliable coolant circulation.

Key Features:

• EPDM (Ethylene Propylene Diene Monomer) construction with synthetic fiber knit reinforcement for superior durability
• 1-inch inside diameter on both ends for consistent flow
• 15.25-inch centerline length for precise fitment
• Pre-molded design eliminates the need for internal spring support
• Engineered to resist electrochemical degradation (ECD), the leading cause of coolant hose failure
• Heat and ozone resistant EPDM cover withstands extreme temperatures from -40°F to +275°F
• Meets SAE 20R3 EC Class D1 specifications for quality and performance
• Resists vacuum collapse and chemical coolant breakdown

Gates molded coolant hoses are manufactured to exact specifications, providing a direct replacement solution that saves time and ensures proper system operation. The EPDM material resists the electrochemical reactions that cause micro-cracks in hose tubes, delivering longer service life and greater reliability than standard hoses.
