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.Automotive Oils & FuelsDetects leaks in hydraulic, engine oil and petrol/diesel fluidsSuitable for all oil types (mineral, semi synthetic, synthetic)25ml treats 8-10 litres of petrol engine oil, 3-5 litres of diesel engine oil, 10 litres of hydraulic fluid or 15 litres of petrol/diesel fuel1 x 25ml bottle sold eachCoolant SystemAdd to coolant system to detect leaks in water pipes and radiators25ml treats 10 litres of OAT (pink) or IAT (yellow)1 x 25ml bottle sold eachSurface Wate
