Designed to work with modern refrigerants, the kit includes dedicated snap-on couplers for both R134A and R1234YF low-side ports, graduated measuring capacity, and simple mechanical operation to force fluids into the system safely and predictably.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the injector actually deliver oil into an A\/C system?\u003c\/h3\u003e\n\u003cp\u003eThe injector uses a screw-plunger mechanism inside an aluminum body that pressurizes and forces oil or dye through a low-side check valve into the system while the compressor circulates refrigerant. It connects to the low-side service port so fluid travels with the system refrigerant rather than requiring system depressurization.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAttach the appropriate snap-on quick coupler (R134A or R1234YF) to the vehicle low-side port.\u003c\/li\u003e\n  \u003cli\u003eFill the injector reservoir with the measured fluid and start the A\/C system to circulate refrigerant.\u003c\/li\u003e\n  \u003cli\u003eOpen the safety valve and screw the plunger to push the fluid into the system.\u003c\/li\u003e\n  \u003cli\u003eLaser-engraved scale and included measuring cup keep injected volumes accurate.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich refrigerant systems and fluids is this kit compatible with?\u003c\/h3\u003e\n\u003cp\u003eThe GallopMax kit is made to work with both R134A and R1234YF service ports and accepts POE or mineral oils, fluorescent leak solution, and most A\/C system additives.
