Gates 19245 Premium Molded Heater Hose Dual ID EPDM Coolant Hose

The Gates 19245 is a premium molded heater hose designed for precise OEM-style fitment in today's smaller, tighter-fitting engine compartments. This factory-molded EPDM coolant hose features dual inside diameters (7/16" and 5/8") with a 26-13/16" centerline length, making it ideal for applications requiring diameter transitions.

Key Features:

• Engineered to resist electrochemical degradation (ECD), the leading cause of hose failure
• EPDM rubber construction unaffected by most coolants and non-oil based additives
• Temperature rating: -40°F to 275°F (-40°C to 135°C)
• Meets SAE 20R3 Type EC Class D-1 and D-2 specifications
• Approved for coolant, water, air, and marine applications
• End 1 inside diameter: 7/16" (11mm) | End 2 inside diameter: 5/8" (15mm)
• OEM-quality construction for reliable, leak-free performance

Gates molded coolant hoses are built to OEM specifications and deliver superior durability compared to universal hoses. The precision-molded design eliminates the need for sharp bends and provides a secure fit that resists vacuum collapse and water permeation. Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal performance.
