It is a critical rubber sealing component designed specifically for the cooling systems of Audi vehicles equipped with the 3.0-liter supercharged V6 engine (3.0T).
Detailed Description & Function
Primary Role: This O-ring seals the junction where the engine coolant crossover pipe / water pipe connects to other primary engine parts, such as the cylinder heads or engine block.
It ensures a tight, pressurized seal that prevents coolant leaks. Dimensions: Approximately 40mm x 6mm (with inner specifications around 31.9mm x 3.3mm x 5.3mm depending on exact seating measurements).
Material Composition: Made from specialized, high-grade heat and chemical-resistant rubber (typically Viton or a high-temp silicone/NBR blend) engineered to handle extreme engine bay temperatures and continuous exposure to corrosive antifreeze/coolant mixtures.
Supercession: This part number replaces older Audi part number 06E121119E.
