Csttler 12V EVAP Smoke Machine Portable Leak Detector Kit — Pressure Gauge, Adapters & Spare Bladder

The Csttler 12V EVAP Smoke Machine is a portable automotive leak detector that pumps dense, visible smoke into EVAP and vacuum systems so you can find and fix leaks fast.

Designed for mechanics and DIYers, this all-in-one kit includes a built-in air pump, pressure gauge, delivery hose, adapters and spare bladder so you can begin testing immediately. The unit warms up quickly and produces continuous smoke to pinpoint cracks, loose fittings and vacuum leaks across fuel, intake and EVAP systems on cars, trucks, ATVs, motorcycles and boats.

How does the Csttler smoke machine find leaks so quickly?

The integrated compressor forces smoke into the system under test at controlled pressure while the gauge monitors holding pressure. Any escape route becomes visible as smoke or a pressure drop, so you can locate even small punctures and hard-to-see gasket issues without disassembly.

• Built-in air pump creating 20–25 psi for fast smoke flow
• Visible, continuous smoke within about 10 seconds of startup
• Pressure gauge indicates rising or dropping pressure for leak confirmation
• Adapters and caps let you seal and test many vehicle connections

What accessories come with the kit and what do they let me test?

The Csttler set ships ready to use with clamps, bottles, delivery hose, multiple cone adapters, intake bladder, cap plugs and a spare bladder. That assortment covers most automotive vacuum ports, EVAP canisters and intake openings so you can adapt the machine to different vehicles and systems.

• Smoke delivery hose and intake bladder for connecting to air intakes
• Multiple vehicle cone adapters for varied port sizes and shapes
• Full-size cap plugs to seal large openings and isolate sections
• Pressure gauge and clamps for monitoring and battery connection

How do you operate it safely and what fluids are required?

Operation is straightforward: add 10–15 ml of baby oil or paraffin oil (not included), connect to the vehicle intake, then attach to a 12V battery. The unit features automatic protection to prevent damage and produces non-hazardous smoke when used according to instructions.

• Use only recommended oils; do not exceed 15 ml in the reservoir
• Connect DC 12V battery clamps to start the built-in pump
• Observe pressure gauge—falling pressure indicates a leak
• Unit includes smart protection and is portable for garage or field use

When should I choose this smoke tester over other leak methods?

Choose the Csttler EVAP smoke machine when visual detection, speed and portability matter. It’s faster and less invasive than disassembly, more revealing than soapy-water checks for small leaks, and avoids costly guesswork when troubleshooting drivability or EVAP fault codes.

• Best for EVAP, vacuum, intake and exhaust-connected leaks
• Saves time versus step-by-step part removal or trial-and-error fixes
• Portable for shop technicians and mobile mechanics alike
• Includes spare parts so you can start testing out of the box

Who is this for: The Csttler 12V EVAP Smoke Machine suits professional mechanics, hobbyists and vehicle owners who need a reliable, transportable leak detection tool. If you diagnose engine surging, rough idle, increased fuel consumption, EVAP error codes or persistent vacuum problems, this kit gives a faster path to accurate leak location and repair planning.
