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.
