The TP-8657HD Opti-Pro Plus/EZ-Ject Heavy Duty Kit from Tracer Products is a violet-light LED leak-detection kit for pinpointing refrigerant and fluid leaks.

The kit features the Opti-Pro Plus cordless, true UV leak detection flashlight with on-board recharging. It has power similar to high-intensity 125-watt lamps, according to Tracer. The high-output flashlight makes leaks stand out by providing good contrast when illuminating fluorescent dye.

It also includes an EZ-Ject A/C dye injector with a hose, coupler, and purge fitting. It comes with two EZ-Ject universal A/C dye cartridges and an 8-ounce twin-neck bottle of Dye-Lite All-In-One concentrated dye for oil, fuel, power steering and hydraulic leaks.

The kit also comes with an 8-ounce twin-neck bottle of Dye-Lite water-based dye for coolant and truck/trailer body leaks, an 8-ounce spray bottle of dye cleaner and fluorescence-enhancing glasses. The kit includes a carrying case.
