Robinair 18470 Syringe-Type POE Oil Injector for HV R-1234YF Systems

I purchased this injector in January2012, when I finally went to use it in April it did not function like it was supposed to. I filled it with poe oil and when I pushed in the plunger, it bypassed the plunger seal. It just made a mess. I would like a replacement syringe.

Works great!
