ContiTech 64254 Molded By-Pass and Heater Hose

The ContiTech 64254 is a 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 components in the vehicle's coolant system. Pre-shaped in an original configuration, this hose delivers a precise, factory-style fit for a reliable, leak-free installation.

Key Features:

• EPDM Construction: Tube and cover are made from durable EPDM (ethylene propylene diene monomer) rubber with synthetic knit reinforcement for long-lasting performance
• SAE Certified: Meets or exceeds SAE 20R3EC Class D1 and Class D2 specifications, as well as many OEM specifications
• Broad Coolant Compatibility: Compatible with most coolants including ethylene glycol- and propylene glycol-based coolants, as well as organic acid modified and long-life coolants
• Original Configuration: Pre-molded to match OEM routing and geometry for a proper, no-modification fit
• Temperature and Chemical Resistance: Built to withstand high underhood temperatures and resist degradation from antifreeze solutions

Important: Not for use in fuel or oil transfer applications. The ContiTech 64254 is a direct-replacement molded heater hose designed to restore proper coolant flow and heating system performance.
