Ring UV Dyes
Ring Automotive UV Dyes find leaks quickly and easily. There are a choice of dyes that cover the oil and fuel systems, coolant systems, air conditioning systems and surface water leaks. They are safe to leave in any system, so flushing and refilling the relevant systems after leak detection is not necessary unless required to repair the leak.
Accessories include an inline dye injector for use with the Air Conditioning System Dye, and a cleaner/degreaser to clean up excess dye.
UV light required to show dye leaks.
