ContiTech 64543 Molded Heater Hose

The ContiTech 64543 is a molded radiator hose designed to transfer glycol-based coolants to and from the heater core, by-pass to the radiator, as well as through other components in the vehicle's coolant system. This precision-molded hose provides an original equipment configuration to ensure proper fit and reliable performance in automotive cooling systems.

Key Features:

• EPDM tube and cover with synthetic knit reinforcement
• Compatible with most coolants including ethylene glycol- and propylene glycol-based coolants, as well as organic acid modified, long-life coolants
• Resistant to Electrochemical Degradation (ECR)
• Temperature range: -40°F to 275°F (-40°C to 135°C)
• Meets or exceeds SAE 20R3EC Class D1 and Class D2 specifications

ContiTech hoses feature durable EPDM (ethylene propylene diene monomer) construction that effectively resists heat, ozone, and chemical coolants. The synthetic knit reinforcement provides strength and resistance to collapse, ensuring consistent coolant flow throughout the system. Not for use in fuel or oil transfer applications.
