Mercedes-Benz Heater Hose for OE-Style Fit

This URO HVAC heater hose is built for the water distribution to heater core circuit on select Mercedes-Benz models. It is molded to match the OE hose shape for cleaner routing and easier installation, with materials selected for heat, ozone, and electrochemical degradation resistance.

• Molded to OE heater hose shape for proper appearance and fit
• EPDM construction resists engine heat, ozone, and electrochemical degradation
• Temperature rated from -40°F to 275°F (-40°C to 135°C)
• Direct replacement for heater hose service on select Mercedes-Benz CL500, S320, S420, S500, 300SE, 400SEL, 500SEC, 500SEL, and 400SE applications
• URO 1408301696 for water distribution to heater core routing

Detailed Product Information

Use this heater hose when servicing the coolant path that feeds the heater core on compatible Mercedes-Benz vehicles. The molded profile helps the hose follow the factory routing, which supports a cleaner engine bay layout and reduces the chance of installation issues caused by incorrect hose shape. Part number 1408301696 is a direct-fit replacement for applications where OE-style routing and material durability matter.

This part cross-references VAICO V30-9701 for the same application.

Common Repair Applications

• Cracked or hardened heater hose material
• Coolant seepage at the heater hose run
• Incorrect hose routing after prior repair work
• Heat-related rubber deterioration in the engine bay
• Electrolysis-related internal hose breakdown

Installation Notes and Tips

Verify the vehicle’s heater hose routing before installation and compare the new hose to the removed part. This hose is molded for specific Mercedes-Benz heater core water distribution applications, including 1992-1999 Mercedes-Benz 300SE, 400SE, 400SEL, 500SEC, 500SEL, S320, S420, S500, and 1998-1999 Mercedes-Benz CL500. Confirm the connection points are clean and free of old coolant residue before fitting the hose.

Quality Assurance

URO backs this heater hose with a 24-month unlimited mileage warranty. The EPDM construction is engineered to resist electrochemical degradation, helping protect the rubber from breakdown caused by coolant-system electrolysis.
