ContiTech 64593 Molded Heater Hose

The ContiTech 64593 is a precision-molded heater hose engineered to transfer glycol-based coolants to and from the heater core, through bypass circuits, and between other components in a vehicle's cooling system. Manufactured by Continental — a trusted OEM and aftermarket supplier — this hose is built to match or exceed original equipment specifications for a reliable, leak-free fit.

Key Features:

• EPDM construction — tube and cover are both EPDM rubber with synthetic knit reinforcement for durability and flexibility
• Wide temperature range — rated from -40°F to 275°F (-40°C to 135°C)
• Coolant compatible — works with ethylene glycol- and propylene glycol-based coolants, including organic acid technology (OAT) and long-life coolants
• Electrochemical Degradation (ECR) resistant — protects against internal hose deterioration caused by stray electrical currents
• Meets SAE 20R3EC Class D1 and Class D2 specifications — as well as many original equipment standards
• Exact-fit molded design — pre-shaped for direct OEM-style replacement with no cutting or fabrication required

Not intended for use in fuel or oil transfer applications. The ContiTech 64593 molded heater hose is a professional-grade replacement part designed for straightforward installation and long service life.
