Each kit includes the EZ-50 dye injector assembly, an A/C hose and coupler with check valve and 0.25" flare low-loss fitting, two EZ-Ject dye cartridges and a purge fitting. The compact dye injector requires only one connection to add dye into an AC&R system. The dye cartridges are calibrated to provide precision dosing. Each cartridge contains enough AR-Glo fluorescent dye to treat two gallons (7.6 L) of lubricant, 25 lb (11.3 kg) of refrigerant or 12 tons of cooling.
