The Tracerline EZ-Ject A/C and Fluid Kit, No. TP-8657, pinpoints leaks in A/C and fluid systems. It features the only concentrated, premium-quality, OEM-approved fluorescent dyes in the industry, according to the company. The dyes are used and approved by major OEM manufacturers, including BMW, Chrysler, Ford, GM, Nissan, VW and more. Included in the kit is the TP-8655 OPTI-PRO Plus, a cordless, “true UV” LED leak detection flashlight with convenient on-board recharging. It emits less visible light, making leaks clearer and easier to spot. Its high-output LED provides optimal fluorescent dye response and contrast, ensuring that every leak glows brilliantly.
