Description

The LeakFinder LF400 is a powerful blue light LED leak detection flashlight with an inspection range of 6 feet (2 m). The LF400’s slim design offers the most optimal coverage of a vehicle’s leaking systems – allowing the user to scan for escaping fluorescent dye in the tightest and hardest to reach spaces. The LEAKFINDER brand was designed to be a cost-effective solution for end-users in the automotive aftermarket. The LeakFinder product line is perfect for DIY jobs and small to mid-sized automotive repair shops. The ultraviolet fluorescent universal dye provides the most precise leak detection for all automotive air conditioning systems containing R-134a, R-1234yf, or other widely used refrigerants. Our dyes can find the smallest and most problematic leaks that would otherwise be impossible to detect. They are the perfect tool for finding small, sporadic leaks in cars, truck and other automotive AC and fluid systems. Proudly made in the U.S.A., Tracer Products is a family-owned company with three generations of experience in delivering award-winning professional service and the industry’s most powerful leak detection dyes, inspection lamps and diagnostic tools.
