Frequently Asked Questions

Q: Can I use this oil injector with both PAG and POE oils? A: No, this injector is labeled specifically for PAG oil only. Using it with different oil types risks cross-contamination that can damage expensive A/C compressors and void manufacturer warranties. Robinair makes separate dedicated injectors for POE and other oil types to maintain system integrity.

Q: How much oil can the Robinair 18480 inject at one time? A: The syringe barrel holds approximately 2 ounces of PAG oil per fill, which covers most standard oil additions.
