The OLK-400EZ/E Complete EZ-Ject™ Leak Detection Kit contains everything needed to pinpoint refrigerant leaks in small-to-medium air conditioning and refrigeration systems, including high-pressure R-410A systems. Each leak location is revealed by a bright fluorescent glow. Featured in the kit is the OPTI-LUX™ 400, a powerful, rechargeable violet light LED leak-detection flashlight, which has power comparable to high-intensity 150-W lamps. It has an inspection range of 25 feet (7.6 m) or more. Also included in the kit are the EZ-Ject dye injector, two multidose 0.5 ounce (14.8 ml) universal/polyolester (POE) dye cartridges, a hose assembly with check valve and low-loss fitting, a purge fitting, an 8-ounce (237 ml) spray bottle of GLO-AWAY™ dye cleaner, three drip plugs, an ac/dc charger, and fluorescence-enhancing glasses. All components are packed in a rugged carrying case. Each dye cartridge treats up to 2 gallons (7.6 L) of lubricant, 25 pounds (11.3 kg) of refrigerant, or 12 tons of cooling.
