Frequently Asked Questions
Can I use this oil injector with PAG oil instead of POE?
No, the 18490 is specifically labeled for polyolester oil only. Using PAG oil risks cross-contamination that could damage compressors and void warranties. Robinair makes separate PAG-specific injectors like the 18480 for conventional A/C systems requiring PAG lubricants in standard vehicles.
How much oil can the 18490 injector hold at one time?
The syringe barrel holds approximately 2 ounces (59 mL) of lubricant per injection. For larger oil additions, you'll need to disconnect, refill the barrel, reconnect to the service port, and inject again, or consider a larger capacity tool for bulk oil additions to the system.
Will this work on R1234yf systems found in newer vehicles?
No, this model works exclusively with R134A systems due to different service port connections and pressure specifications. For R1234yf applications in 2013+ vehicles, you need the Robinair 18465 which has the correct fittings and pressure ratings for that newer refrigerant type.
Do I need to evacuate the system before using this injector?
No evacuation required. The 18490 injects oil directly into pressurized systems up to 80 PSI through the low-side port. Simply fill the barrel with oil, connect the coupler, and press the plunger to add lubricant while the system remains charged.
