Automotive Oil Filter Anti-Drainback Valve

The Automotive Oil Filter Anti-Drainback Valve is a crucial component in maintaining engine longevity and performance. It is designed to prevent oil from draining out of the oil filter when the engine is turned off, ensuring that the filter remains full of oil and ready to deliver immediate lubrication upon startup.

Prevents Oil Drainage
The primary function of the Automotive Oil Filter Anti-Drainback Valve is to hold oil in the filter after the engine is shut down. This mechanism is essential for preventing the delay in oil pressure buildup once the engine is restarted. Without this valve, the pressurized oil would have to fill the filter before reaching the engine's critical components, to potential initial wear due to a lack of lubrication.

High-Quality Silicone Membrane
All Automotive Oil Filter Anti-Drainback Valves feature a flexible membrane made of high-quality silicone. Positioned on the dirty side/entrance of the filter, this silicone membrane is resilient and durable, ensuring that it effectively seals and prevents oil from draining back into the oil pan when the engine is off. This design contributes to the valve's reliability and efficiency in maintaining oil within the filter.
