Audi VW A/C Refrigerant Discharge Hose - Genuine VW Audi 1K0820721BL

Product Information

An A/C refrigerant discharge hose is a high-pressure hose that connects the air conditioning compressor to the condenser in a vehicle’s A/C system. After the compressor compresses the refrigerant gas, the discharge hose carries this hot, high-pressure refrigerant to the condenser, where it is cooled before circulating through the rest of the system. Because it handles both high pressure and high temperature, it is made of reinforced rubber or synthetic materials to withstand demanding conditions.

• Weak or no cooling from the A/C due to loss of refrigerant pressure from leaks in the hose.
• Visible refrigerant oil residue or cracks along the hose, sometimes accompanied by a hissing sound.
• A/C system warning lights or compressor cycling frequently because the system cannot maintain proper pressure.

About Genuine VW Audi

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 VAG to build your car are available as replacement parts under the “Genuine VAG” brand. Manufactured under the direction of VAG, expect excellent quality and a premium price since these parts are available exclusively through the VAG Dealership network.

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

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct 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.
