Stop guessing where the leak is. This professional Automotive Smoke Machine Accessories Kit gives you the exact tools needed for fast, accurate EVAP and vacuum leak detection. Engineered for real-world use, the kit features a high-performance inflatable intake adapter that expands to seal odd-shaped ports securely, plus 7 precision multi-size sealing cones covering 0.6cm to 6.5cm diameters. These cones are made from high-density, heat-resistant rubber with textured grip for maximum sealing power on everything from tiny vacuum hoses to large truck intakes. You also get a universal cone adapter, standard cap plug, dual-head valve core remover for direct EVAP port access, and a heavy-duty 410 stainless steel hose clamp that keeps everything locked tight under pressure. No more smoke leaks, slipping plugs, or makeshift fixes with tape.

Compatible with nearly all 12V automotive smoke machines, it turns basic leak testing into a professional-grade diagnostic process.
