This automotive smoke machine leak detector is designed for routine leak detection in EVAP systems, vacuum hoses, intake passages, and light exhaust systems. It produces visible smoke to help trace leak locations quickly and uses a built-in air pump for standalone operation without an external pump. Adjustable low- to mid-pressure output supports different testing needs while remaining suitable for sensitive components. The included sealing adapters help improve testing accuracy across common vehicle ports and hoses. It is suitable for cars, motorcycles, and boats.
