Robinar Oil Injector

The Robinair R134a oil injector with 1/2" ACME quick coupler is a syringe-type injector designed for adding oil to a fully pressurized A/C system. It's handy for adding dyes to A/C for leak detection. Fill the barrel with the amount of oil needed (measurements are marked on the barrel body), connect the injector fitting to the low side access port on the vehicle and press the plunger to deliver the oil charge. It can also be used for fluorescent dyes.
