When applied to an air conditioning system, Air Con Dye will mix with the refrigerant and circulate throughout the system. At the area of the leak, a small amount of UV dye will escape and stain the area with a fluorescent dye, allowing the operator to see this with the aid of the UV lamp and enhancing glasses. A repair can then be conducted to the affected area. Universal A/C dye is compatible with all refrigerants up to R134A.


The injection gun injects the dye into the A/C system without the need to evacuate any refrigerant. To use, proceed with the following steps:
1. Set up the UV injection gun and hose as per the instructions on the UV Gun/Hose Customer Data Sheet.

Remove the drip cap from the R-134a adapter
then connect the gun to the low side port of the A/C system. (Fig.4)
2. Inject dye into the A/C system by squeezing the trigger twice. This is enough dye for a typical vehicle. For smaller systems, squeeze the trigger only once.
3. Disconnect the adapter from A/C system
then attach the drip cap to the adapter hose.
