The kit includes both R134A and R1234YF quick couplers, a 2 oz hand‑turn clear oil cylinder, and a brass hose assembly so you can add oil or dye precisely when the system is off or under service conditions.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the injector get oil or dye into a system without the compressor running?\u003c\/h3\u003e\n\u003cp\u003eThe Aupoko injector uses a screw‑in piston design and a one‑way check valve to push fluid directly into the low‑side service port. This eliminates the need to operate the compressor during injection, which is useful for systems that are low on oil or cannot be run safely.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eHand‑turn screw mechanism for controlled displacement\u003c\/li\u003e\n  \u003cli\u003eBuilt‑in check valve prevents backward flow into the cartridge\u003c\/li\u003e\n  \u003cli\u003eClear 2 oz cylinder lets you watch the volume injected\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich refrigerants and oils is this compatible with?\u003c\/h3\u003e\n\u003cp\u003eThe kit is built to work with common mobile and light HVAC refrigerants like R134A and newer R1234YF, and it accepts POE and mineral oils as well as standard fluorescent dyes.
