ContiTech 64686 Elite Engine Coolant Molded Radiator Hose

The ContiTech 64686 is an Elite™ engine coolant molded radiator hose engineered to transfer glycol-based coolants to and from the radiator and through other components of the vehicle's cooling system. Pre-shaped to match OE contours, this hose installs cleanly without cutting or adapting, delivering a precise, leak-free fit.

Key Features:

• EPDM Construction: Made from ethylene propylene diene monomer (EPDM) synthetic rubber, offering excellent resistance to heat, ozone, and chemical coolants
• Synthetic Knit Reinforcement: Internal Tylanar knit reinforcement provides burst strength that meets or exceeds SAE standards
• Wire Insert: Integral wire insert resists hose collapse under vacuum, ensuring full, unobstructed coolant flow at all times
• Corrugated Cover: The corrugated outer cover allows the hose to follow the bends of the OE coolant hose naturally without kinking
• Electrochemical Degradation (ECR) Resistant: Formulated to resist the electrochemical degradation that can occur in modern cooling systems
• Meets SAE 20R4EC Class D1: Built to meet or exceed strict SAE specifications for radiator hose performance and safety

ContiTech is an ISO/TS 16949-certified manufacturer and a trusted OE supplier, making the 64686 a direct-fit, OEM-quality replacement for worn or deteriorating coolant hoses. Compatible with all standard glycol-based automotive coolants.
