Check Valve

About this product

The Check Valve (#90917-10049), a key component in Toyota's Drive-Chassis Transfer Vacuum Piping system, Engine-Fuel Air Cleaner system, and the Engine-Fuel Vacuum Piping system, plays a critical role in controlling the flow of fluids or gases. This valve allows movement in one direction only, thus preventing backflow. Its mechanism includes an inlet port, an outlet port, and a movable disc that opens or closes depending on the flow direction. This disc shuts off when flow tries to reverse, protecting system components from damage or contamination. However, over time, the Check Valve (#90917-10049) may degrade, become clogged, or even break, which can lead to fluid or gas backflow, reduced system efficiency, or complete failure. As such, periodic replacement using genuine Toyota parts is crucial to maintain compatibility and optimal performance. These authentic parts come with Toyota's genuine parts warranty. By ensuring a one-way fluid or gas flow, the Check Valve (#90917-10049) contributes significantly to the safety and efficiency of the systems it serves.
