The Tracerline® OPTI-PRO™ Plus/EZ-Ject™ Heavy Duty Kit (P/N TP-8657HD) makes it easy for technicians to find all refrigerant and fluid leaks quickly and efficiently. The kit features the OPTI-PRO™ Plus, a cordless, ultra-compact, true UV (violet light) leak detection flashlight with convenient on-board recharging. With power comparable to high-intensity 125 watt lamps, the high-output UV LED provides optimal fluorescent dye response and contrast, causing each and every leak to glow brilliantly. Included in the kit are an EZ-Ject™ A/C dye injector with hose/coupler and purge fitting, two EZ-Ject universal A/C dye cartridges, and an eight ounce twin-neck bottle of Dye-Lite®: All-In-One™ concentrated oil dye for oil, fuel and hydraulic leaks. Also included are an eight ounce twin-neck bottle of Dye-Lite® water-based dye for coolant leaks, an eight ounce spray bottle of dye cleaner and fluorescence-enhancing glasses. All components are packed in a rugged carrying case.
