Frequently asked questions
What refrigerants does the A/C dye work with?
The included MPD™ A/C dye concentrate is safe for R-12 and R-134a systems, and the kit also includes a dedicated 1 oz bottle of dye for R-1234yf systems — so you’re covered across older and current A/C systems.
Is the Versa Light UV flashlight rechargeable?
Yes. The Versa Light runs on an included 18650 Li-ion rechargeable battery and comes with both a USB charging cord and a wall charger. A built-in indicator shows green above 70% charge and red below 30%.
How many leak detection applications does the kit include?
The kit provides up to 52 applications of A/C, coolant and oil/fluid dye — a retail installed dye value of over $520 — making it one of the most complete leak detection start-up kits available.
Can I use it for coolant and oil leaks, not just A/C?
Absolutely. Along with A/C dye, the kit includes dedicated MPD™ coolant dye and oil/fluid dye, so you can trace leaks in cooling systems, engine oil, transmission fluid, power steering and hydraulic systems too.
