Type 25 Syncro Carb Base Gasket - 1.9 Waterboxer

This genuine Volkswagen carburettor base gasket is designed specifically for Type 25 / T3 Syncro buses fitted with 1900cc petrol engines. It fits between the carburettor and the inlet manifold, providing a correct factory seal that is essential for reliable carburettor operation on Syncro models.

The carb base gasket plays a critical role in sealing the intake system. Any air leaks at this point can cause poor idle quality, hesitation, lean running, and reduced drivability—issues that are especially noticeable on carburetted engines. Being a Genuine VW part, this gasket is manufactured to the exact material specification, thickness, and profile originally fitted by Volkswagen, ensuring long-term reliability and perfect fit.

Syncro models place additional demands on engine components due to drivetrain layout and operating conditions, making correct intake sealing particularly important. Replacing the carb base gasket is strongly recommended whenever the carburettor is removed or if intake leaks are suspected.

How it works

The gasket seals the mating surface between the carburettor base and the inlet manifold, preventing unmetered air from entering the engine. This ensures the carburettor can maintain the correct air–fuel mixture across all driving conditions.
