AutoLine Pro Smoke Fluid UV Leak Tracing Solution — Bright UV Glow (395nm), Long-Run 700‑Min Output

AutoLine Pro Smoke Fluid is a lab-formulated, ultra-pure UV-reactive smoke solution that produces exceptionally bright fluorescence for fast, reliable automotive leak tracing.

Designed and tested in California, this smoke fluid delivers a clean, dense vapor that retains strong UV brightness even after vaporization, making fluorescent leak detection easier and faster across EVAP, vacuum, intake, exhaust and many other systems. The formula minimizes residue and equipment wear compared with lower-quality alternatives. Note: not compatible with AutoLine Pro’s VENTUS smoke machine — use VENTUS Fluid for that model.

How does this fluid improve leak detection speed and visibility?

The fluid is optimized to fluoresce most strongly at about 395 nm, giving a vivid glow under the correct UV flashlight so technicians can pinpoint leaks quickly. Its brightness persists after vaporization, unlike many competitors that dim or fade when heated.

• Formulated for maximum UV intensity at 395 nm for clearer fluorescence.
• Maintains brightness after passing through the smoke generator.
• Dense, thick smoke highlights small leaks and slow seepage effectively.
• Helps reduce inspection time by improving visual contrast under UV light.

Will this fluid harm my smoke machine or vehicle components?

AutoLine Pro’s formulation emphasizes ultra-purity to limit buildup, deposits, or damage to sensors and internal surfaces when used as directed. It was engineered and vetted to avoid the common corrosive or coating effects associated with low-grade fluids.

• Ultra-pure base reduces residue and internal coating risk.
• Lab-tested to be safe with common smoke machine materials (follow manufacturer instructions).
• Not intended for AutoLine Pro VENTUS — use that model’s specified fluid to preserve its zero-odor system.

Which leak-testing scenarios and equipment does this fluid suit best?

This smoke fluid is formulated for broad automotive applications: EVAP systems, vacuum lines, intake and exhaust, turbo and supercharger housings, EGR components, cooling and engine block inspections, and body/trim leak checks. It is compatible with AutoLine Pro units and most other commercially available smoke machines.

• EVAP, vacuum, intake, exhaust, turbo/supercharger, EGR, cooling systems, engine blocks.
• Works with AutoLine Pro smoke testers and most third-party smoke machines.
• Each bottle provides up to 700 minutes of continuous, steady thick smoke.

How much smoke does one bottle produce and what performance can I expect?

Each bottle is formulated to deliver long-duration output so a single bottle covers many diagnostic sessions without frequent refills. The concentrated formula yields steady, thick smoke for up to 700 minutes of continuous operation under typical machine settings.

• Up to 700 minutes of continuous, dense smoke per bottle.
• Consistent output suitable for prolonged diagnostic work or multiple jobs.
• Reduces downtime and refill frequency on busy service benches.

Who is this for: Professional technicians, independent repair shops, mobile mechanics, and serious DIYers who need a high-visibility, lab-tested UV smoke fluid for comprehensive leak tracing across automotive systems. Choose AutoLine Pro Smoke Fluid when you want a bright, ultra-pure tracer that’s compatible with most smoke machines — and remember to use VENTUS Fluid for AutoLine Pro’s VENTUS model.
