R-1234yf Heavy Duty A/C Oil Injector

The AirSept R-1234yf Heavy Duty A/C Oil Injector combines a large sight glass, with easy-to-read measurement scales, and a quick connect coupler that is configured for R-1234yf service ports. A Pyrex inner wall functions as a full-body sight glass, allowing technicians to see they are injecting the desired amount of fluid. The tool provides greater accuracy, extended O-ring life and reduced leakage. The smooth inner wall eliminates O-ring abrasion that occurs with rougher machined aluminum injectors. Higher injecting pressure - up to 230 psi (16 bar) - gives greater flow in high ambient applications. Other benefits include a 2mm thick high-impact transparent shell to protect against damage and large square cut threads for piston movement that maintains injecting accuracy.
