Continental 64628 HVAC Heater Hose - Heater Inlet or Heater To Engine

Continental Molded HVAC Heater Hose 64628

Continental 64628 is a molded HVAC heater hose built for coolant transfer between the heater core, bypass circuit, radiator, and related engine cooling components. With a 0.650-inch inside diameter at both ends and an 18.000-inch length, it is shaped for direct routing in applications that require a formed hose profile.

This Continental Molded hose line focuses on OE-style fit and material performance for heater circuit service. Part number 64628 is made to meet SAE 20R3EC Class D1 and D2 requirements and is resistant to electrochemical degradation, helping maintain hose integrity in coolant systems.
