Fel-Pro Volkswagen Passat 35831 Engine Coolant Pipe O-Ring

What you get here is a single Engine Coolant Pipe O-Ring from Fel-Pro, part number 35831. This O-ring is specifically made to seal the engine coolant pipe, which is a pretty important job to keep your engine running at the right temperature. If this seal starts to leak, you can end up with coolant loss and overheating issues, so having a good, solid O-ring is key.

Fel-Pro designs these O-rings for the real-world repair environment, meaning they're built to handle imperfect sealing surfaces, which can sometimes happen during a repair. They use proprietary materials to make sure you get a reliable seal. This particular O-ring is application-specific, so it's made to fit right on a wide range of Audi and Volkswagen vehicles, like the Audi A4, Volkswagen Passat, and Audi A6, among others. It meets or exceeds original equipment specifications, giving you confidence that it will perform as expected.
