ContiTech 63091 Molded Heater Hose

The ContiTech 63091 is a premium molded heater 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 molded configuration ensures a precise, factory-like fit for specific vehicle applications.

Construction and Materials:

• EPDM (ethylene propylene diene monomer) tube and cover for superior durability
• Synthetic knit reinforcement for strength and flexibility
• Molded design provides exact-fit installation
• Inner diameter: 0.625 inches (5/8") at one end, 0.750 inches (3/4") at the other
• Approximate length: 10 inches

Performance Specifications:

• Temperature range: -40°F to 275°F (-40°C to 135°C)
• Meets or exceeds SAE 20R3EC Class D1 and Class D2 specifications
• Resistant to Electrochemical Degradation (ECD/ECR)
• Compatible with ethylene glycol and propylene glycol-based coolants
• Compatible with organic acid modified (OAT) and long-life coolants

This heater hose is designed for applications that endure higher underhood temperatures and require exceptional heat resistance. The molded construction eliminates guesswork during installation and ensures proper routing through tight engine compartments. Not for use in fuel or oil transfer applications.
