Alide Vacuum Check Valve for VW/Audi, 2 pcs.

Vacuum check valve for the engine system

A set of two vacuum check valves intended for many Volkswagen and Audi models, including VW Jetta (1987-1999), EuroVan (1993-2003), T2/T3/T4/T5, Golf (1985-1988), Passat (1990-2005), Corrado (1990-1994) and Audi A6 (1995-2004), Audi Coupe and Cabriolet. These valves are part of the engine vacuum system, which is involved, among other things, in controlling brake booster elements and other components that use vacuum.

Principle of operation

A check valve allows air to flow in one direction only, blocking reverse flow. Thanks to this, the engine vacuum system keeps working stably and air does not flow back in an undesired direction, which could disturb the operation of vacuum-powered components.

Material and construction

The valves are made of durable PVC plastic, resistant to corrosion and typical wear, which ensures long-lasting, stable operation in the engine bay.

Package contents

The package contains two valves, which lets you keep a spare for the future or replace two valves in the vehicle's system at once.

Part numbers

Compatible with OEM numbers: 433862117 and 1168000378. Before buying, it is worth verifying compatibility with your specific vehicle model and year.
