5Q0-253-115-B Genuine VW/Audi Turbocharger Outlet Sealing Ring

Genuine VW/Audi turbocharger outlet sealing ring, part number 5Q0-253-115-B. This exhaust gasket seals the matching connection between the turbocharger outlet and converter inlet pipe. The ring sits at the mating connection and works with its specified clamp to keep exhaust gas within the exhaust path.

Technical details

• Original part number: 5Q0-253-115-B / 5Q0253115B.
• Annular exhaust sealing ring for the specified turbocharger-to-converter connection.
• The product photo shows the ring's circular profile and sealing edge.
• Supplied as one sealing ring. The clamp, converter, pipe and turbocharger are separate.
• Match the factory flange and clamp design; this ring is not interchangeable with every bolted exhaust gasket or aftermarket downpipe seal.

Common reasons to replace

Replacement is appropriate when the matching joint is opened for turbocharger or exhaust service, or when the old seal is damaged and no longer seals reliably. Heat cycling, corrosion at the connection or a misaligned joint can contribute to leakage.

Soot at the connection, a ticking or blowing sound and exhaust odor warrant inspection. A loose or damaged clamp, cracked pipe or distorted flange can cause similar symptoms. Inspect these components rather than assuming that the sealing ring alone will resolve the leak.

Installation and service notes

Let the exhaust cool before service and support the pipe assembly while releasing the connection. Remove the previous ring, inspect the flange seats and check the clamp for damage. Seat the replacement in the specified location without twisting or trapping it between misaligned surfaces.

Align the pipe and turbocharger outlet before tightening the clamp. Use the required hardware and vehicle-specific tightening procedure; do not use clamp force to pull a strained exhaust into position. Check the nearby support brackets and exhaust clearance, then verify the assembled joint for leakage.

Fitment

Confirm the original outlet connection and seal assignment before ordering. For modified turbochargers or downpipes, compare the flange design directly.
