Smoke Leak Detector 12V EVAP Vacuum Tester for Cars

A 12V smoke leak detector for cars, trucks, vans and motorcycles, used to help locate leaks in pipe systems. It is suitable for checking EVAP fuel pipes, air intake systems and radiator pipework, giving a clear way to trace faults that can be difficult to find by sight alone.

Used for vehicle diagnostics, servicing and repair work, this tester helps when chasing vacuum leaks, intake leaks or small pipe faults that can affect running, emissions or cooling performance. It suits garage work, workshop use and home mechanics carrying out fault finding on cars or motorcycles, especially where a leak is suspected but not immediately visible. The smoke output makes it easier to track where air or vapour is escaping, which can save time during inspection and repeated checking.

Powered by a 12V vehicle battery, the unit has a built-in air pump, so there is no need for a separate air supply. Adjustable flow gives more control during testing, while the stated smoke output of 1 to 6L per minute and output pressure of 10 to 18psi cover a range of common diagnostic jobs. A 100ml oil capacity supports repeated testing, and the supplied tubes, stoppers and adaptors help with sealing and connecting to different pipe openings. The automatic power-off protector adds a useful safety feature during use, and the included fittings help keep testing straightforward when working across different systems.
