Vacuum Pump
A tool that generates vacuum pressure for testing and bleeding vehicle systems.

A hand or electric vacuum pump creates suction used to test EGR valves, vacuum lines, and brake boosters. It also aids in bleeding hydraulic brake systems by removing trapped air. The gauge attached to the pump allows precise pressure control. Vacuum pumps are indispensable for diagnosing vacuum leaks, ensuring proper system sealing, and performing fluid service. Proper use prevents brake failure and supports accurate emission control testing.
