ContiTech 64561 Molded By-Pass Heater Hose

The ContiTech 64561 Molded By-Pass Heater Hose is a precision-molded coolant hose engineered to transfer glycol-based coolants to and from the heater core, by-pass to the radiator, and through other components in your vehicle's cooling system. This pre-formed hose is designed to match the exact configuration of the original equipment part for a proper fit and reliable performance.

Key Features:

• EPDM (ethylene propylene diene monomer) tube and cover construction for superior heat and chemical resistance
• Synthetic knit reinforcement provides strength and durability
• Meets or exceeds SAE 20R3EC Class D1 and D2 specifications as well as OE requirements
• Compatible with ethylene glycol and propylene glycol-based coolants, including long-life organic acid modified coolants
• Pre-molded configuration assures proper fit and easy installation
• Resistant to high underhood temperatures, ozone, and chemical coolants

This molded heater hose is designed as a direct replacement for worn or damaged factory hoses, restoring proper coolant flow and system operation. The EPDM construction provides excellent resistance to the harsh underhood environment while maintaining flexibility for reliable, long-lasting performance.
