ContiTech 64249 Molded By-Pass and Heater Hose EPDM

The ContiTech 64249 is a precision-molded by-pass and heater hose engineered to transfer glycol-based coolants to and from the heater core, by-pass to the radiator, and through other critical components in the vehicle's coolant system. Pre-shaped in original configurations, this hose delivers an exact OE-style fit for hassle-free installation.

Key Features:

• EPDM construction — tube and cover with synthetic knit reinforcement for superior durability and long service life
• Meets or exceeds SAE 20R3EC Class D1 and Class D2 specifications as well as many original equipment (OE) specifications
• Electrochemical Degradation (ECR) resistant — protects against the internal hose deterioration caused by coolant chemistry and electrical currents
• Compatible with most coolants — including ethylene glycol- and propylene glycol-based coolants, as well as organic acid modified long-life coolants
• ID range: 1/4" to 1-3/8", including intersect hose configurations
• Temperature range: -40°F to 275°F (-40°C to 135°C)
• Original molded configurations ensure proper routing and a secure, leak-free fit

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