Description

UV fluorescent leak detection. UV dyes easily pinpoint hard-to-find leaks in minutes. Leakfinder dye products are the solution for anyone working on fluid-based systems. No. Leakfinder dyes never need to be removed. In fact, they are designed to stay in the system so you can easily recheck the repair and find future leaks. Step 1: ADD the appropriate dye to the suspect system & run the system to circulate the dye. Step 2: INSPECT the system with a leak detection flashlight & all leaks will glow brightly. Proudly manufactured in the U.S.A., Tracer Products has over 65 years of experience delivering professional service and the industry’s most powerful leak detection dyes, inspection lamps, and diagnostic tools. The Leakfinder brand offers the brightest, most cost-effective, and efficient solutions for finding AC and fluid-based vehicle leaks. What does LeakFinder help me do? LeakFinder helps you find common vehicle leaks faster. Add the correct UV dye, let it circulate, then scan with a UV light. Leaks glow brightly so you can see where the problem is coming from. What kinds of leaks can I check with LeakFinder? LeakFinder offers simple options for A/C leaks, coolant leaks, and oil-based leaks. Depending on the dye selected, it can help check areas like hoses, fittings, radiators, engine oil systems, transmission fluid systems, and power steering systems. Is LeakFinder easy to use? Yes. LeakFinder is designed to make leak detection simple: add dye, run the system, and scan for the glow. It is a practical choice for DIYers, vehicle owners, and small shops. Do I need a special light to see the dye? Yes. LeakFinder UV dye needs a compatible UV or violet leak detection light to glow. Some kits include a light, while dye-only products may require a light to be purchased separately. How does LeakFinder help save time? LeakFinder helps show the source of the leak instead of relying on guesswork. Once the dye glows, you can focus on the leaking area and decide what repair is needed.
