The Tracerline OPTI-PRO Plus/EZ-Ject Heavy Duty Kit, No. TP-8657HD, pinpoints refrigerant and fluid leaks. The cordless, compact OPTI-PRO Plus UV leak detection flashlight has on-board recharging capabilities and provides power comparable to 125-watt lamps. The UV LED provides optimal fluorescent dye response and contrast, causing leaks to glow. The kit includes an EZ-Ject A/C dye injector with hose/coupler and purge fitting, two EZ-Ject A/C dye cartridges and an 8 oz twin-neck bottle of Dye-Lite oil dye for oil, fuel ATF, power steering and hydraulic leaks. An 8 oz twin-neck bottle of Dye-Lite water-based dye for coolant and truck/trailer body leaks, an 8 oz spray bottle of dye cleaner and fluorescence-enhancing glasses are also in the carrying case.
