Audi VW A/C Line O-Ring Front (Q7 Touareg) - Genuine VW Audi 7H0819737

Product Information

The A/C line O-ring is a small, rubber gasket that creates a seal between the various connections in an automotive air conditioning system, such as the A/C lines, hoses, compressors, and other components. Its primary purpose is to prevent refrigerant and lubricant from leaking out of the A/C system. O-rings are critical in maintaining the efficiency and functionality of the air conditioning system.

• Refrigerant Leaks: The most common sign of a failing A/C line O-ring is a refrigerant leak. You may notice a drop in the performance of the air conditioning system, as refrigerant escapes from the leak point. Leaking refrigerant may also leave a visible oily residue around the connection points of the A/C lines.
• Refrigerant Recharging: If the A/C system requires frequent recharging with refrigerant, it could be due to a slow leak caused by a worn or damaged O-ring. Recharging the refrigerant without addressing the leak will only provide temporary relief, and the problem will recur.

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.
