Product Information

Mercedes-Benz AC Hoses and Pipes diagram for C240, C280, C320

An A/C refrigerant suction hose is a flexible hose in a vehicle’s air conditioning system that carries low-pressure refrigerant from the evaporator (inside the cabin) back to the compressor. It’s part of the closed-loop refrigerant circuit and is designed to handle low-pressure, low-temperature refrigerant in gas form.

These hoses are usually made of reinforced rubber or synthetic materials with metal fittings at each end to withstand pressure changes and vibration.

• Reduced Cooling Performance: The A/C may blow warm or less cold air due to refrigerant loss or restricted flow.
• Hissing or Bubbling Noise: A refrigerant leak in the hose can cause audible hissing when the system is running.
• Visible Refrigerant or Oil Leaks: Refrigerant often carries a small amount of oil; oily residue or wet spots around hose connections can indicate failure.

About Genuine Mercedes

You may not realize this, but the parts that make up your Mercedes-Benz are not necessarily manufactured by Mercedes-Benz.

In fact, many of these manufacturers have been making parts for Mercedes-Benz for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Mercedes-Benz parts box and find an OEM branded part inside, simply with the addition of a Mercedes-Benz logo.
