ContiTech 64627 Molded Heater Hose HVAC Coolant Hose

The ContiTech 64627 is a precision-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 the vehicle's coolant system. Pre-shaped to an original equipment configuration, this hose delivers a reliable, leak-free fit without cutting or bending.

Key Features:

• EPDM construction — tube and cover manufactured from ethylene propylene diene monomer rubber for superior resistance to heat, ozone, and chemical degradation
• Synthetic knit reinforcement — provides added strength and dimensional stability under pressure
• Broad coolant compatibility — works with ethylene glycol-, propylene glycol-based, and organic acid modified long-life coolants
• Meets or exceeds SAE 20R3EC Class D1 and Class D2 specifications as well as many OE specifications
• Electrochemical Degradation (ECR) resistant — guards against internal hose breakdown caused by electrolytic activity in the coolant system
• Temperature range: -40°F to 275°F (-40°C to 135°C)
• Original molded configuration for a direct, proper fit

Important: This hose is intended for coolant system applications only. Not for use in fuel or oil transfer applications.

ContiTech molded heater hoses are a trusted OE-quality replacement, restoring proper coolant flow and heater performance to factory standards.
