Anti-Drain Valves

Also known as the Anti-Reflux valve, the purpose of the anti-drain valve is to prevent the oil from draining out/escaping the oil filter when the engine is turned off.

This valve is very crucial to your car’s engine life. When the engine is turned off, if the valve is damaged or faulty, the oil would drain out, and when it is switched on the next time, there would be no oil available to immediately lubricate the engine, leading to wear and damage.

It is usually in the form of rubber and obscures the passages which leads to oil drainage. Bosch uses a high-quality silicone body as the anti-drain valve and ensures no oil spills when you turn your car off. These oil filters have the least reported complaints of damaged anti-drain valves, even when checked during routine oil and filter changes.


Bosch only uses premium materials in the manufacturing of its products, and when you unbox the premium Bosch oil filters, you immediately get the idea by just even touching them.

The premium range of oil filters is made of high-quality stainless steel as the main material. The perfect fit and finish of the steel housing ensure n leakage or loose fitting, while the silicone anti-drain valve forms a tight seal to prevent leakage of oil.

The main filter media is a woven mesh of pure fiber blended with glass, to ensure 99% filtration of harmful particles and long-term serviceability. Your car would enjoy a sigh of relief when the Bosch oil filter is regulating the flow of oil through the engine, thanks to its top-quality and durability.
