ContiTech 64613 Molded Heater Hose

The ContiTech 64613 Molded Heater Hose is a precision-formed coolant hose engineered to transfer glycol-based coolant to and from the heater core, through bypass circuits, and to other components within the vehicle's cooling system. Pre-molded to an exact OE configuration, this hose delivers a direct-fit replacement that simplifies installation and restores proper cooling system function.

Key Features:

• EPDM construction — tube and cover made from EPDM rubber with synthetic knit reinforcement for long-lasting durability and heat resistance
• OE-matched configuration — pre-molded shape mirrors the original equipment design for a proper, leak-free fit
• Broad coolant compatibility — works with ethylene glycol-based, propylene glycol-based, and organic acid modified long-life coolants
• Electrochemical Degradation (ECR) resistant — resists the internal electrochemical corrosion that can cause premature hose failure
• Meets or exceeds SAE 20R3EC Class D1 and D2 specifications — as well as many original equipment manufacturer (OEM) standards
• Temperature range: -40°F to 275°F (-40°C to 135°C)
• ID Range: 1/4 in. to 1-3/8 in., including intersect hose configurations

Important: Not intended for use in fuel or oil transfer applications. This heater hose is a direct OE replacement designed for automotive heater core and coolant bypass circuits only.
