AutoLine Pro Smoke Fluid UV Leak Tracer — Brightest 395nm Glow, 700‑Min Runtime for EVAP & Vacuum

AutoLine Pro Smoke Fluid is a lab-developed, ultra-pure UV‑visible smoke solution engineered to deliver the brightest, longest-lasting leak-tracing smoke for automotive EVAP, vacuum, intake, exhaust and general smoke testing.

Designed and tested in California, this formulation focuses on clean output and strong UV fluorescence at ~395 nm so leaks show up vividly under a compatible UV flashlight. It is optimized for use with most smoke machines, yielding sustained thick output without leaving damaging residues on internal sensors or machine components. Note: do not use this fluid in the AutoLine Pro Ventus machine — Ventus requires its own Ventus Fluid.

How does this fluid make leaks easier to find?

The bright UV tracer in this smoke fluid fluoresces under near‑UV light, highlighting leak paths and escape points that standard smoke can miss. Because the dye remains visible after vaporization, it creates a clear, glowing trail where air is escaping.

• Formulated to glow strongest at 395 nm for clear fluorescence.
• Produces thick, steady smoke that clings to leak locations.
• High-contrast visibility under UV flashlights improves detection speed.

Will this fluid harm my smoke machine or vehicle components?

No—AutoLine Pro’s formula was developed to minimize buildup and protect internal parts when used correctly. The ultra-pure base reduces the risk of coating sensors or creating sticky residues that can occur with lower-quality fluids.

• Lab-tested for purity to limit internal deposits.
• Compatible with the majority of commercial smoke testers and brands.
• Avoid using in Ventus machines; Ventus requires its dedicated fluid.

How long does one bottle last during continuous use?

Each bottle is formulated to provide extensive run time—enough for multiple diagnostic sessions—so you’ll spend less time refilling and more time troubleshooting. The thick smoke output maintains density over long periods to support extended testing needs.

• Up to 700 minutes of continuous thick smoke output per bottle.
• Consistent performance across prolonged diagnostic jobs.
• Reduces downtime during multi-stage inspections or workshops.

What systems and applications is this fluid suitable for?

AutoLine Pro Smoke Fluid is formulated for broad automotive and workshop use, from EVAP system diagnostics to vacuum and intake checks. It also works well for general leak tracing on turbo, supercharger, cooling, exhaust and bodywork systems.

• EVAP, vacuum, intake, exhaust, turbo and supercharger inspections.
• Cooling systems, EGR, engine blocks and bodywork leak tracing.
• Useful in shop, field diagnostics, and training scenarios.

Who this is for: technicians, independent shops, fleet maintenance teams and serious DIYers who need a reliable, high‑visibility smoke tracer to find subtle or elusive leaks fast. If you operate an AutoLine Pro Ventus smoke machine, purchase the Ventus Fluid specifically; for all other smoke testers, this product offers a lab-proven balance of brightness, purity and long runtime to speed diagnostics without compromising equipment longevity.
