With the simplicity of Yellow Jacket® Universal A/C Dye Solutions, you need only one fluorescent dye for systems with mineral, alkyl, or polyol ester lubricants. Injection is fast and easy. Once the universal dye is injected into the system, pinpoint leaks quickly with a Yellow Jacket fluorescent leak scanner, including: the palm-size Micro UV leak detector; the Universal Pure UV System for increased UV transmission; and the AC-powered pistol-grip lamp.
