VW A/C Low Pressure Line - Genuine VW 1J1820743AG

Product Information

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 VW

The Volkswagen Group, also known as “VAG”, consists of Volkswagen, Audi, Lamborghini, Bentley, Bugatti, Porsche, Ducati, MAN, Scania, SEAT, and Skoda. The original parts used by VW to build your car are available as replacement parts under the “Genuine VW” brand. Manufactured under the direction of VW, expect excellent quality and a premium price since these parts are available exclusively through the VW Dealership network.

You may not realize this, but the parts that make up your VW are not necessarily manufactured by VW. No cause for concern, as VW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for VW 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 VW parts box and find an OEM branded part inside, simply with the addition of a VW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming directly from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
