The injector includes a 1\/4\" SAE port with a built-in backflow check valve, making it suitable for leak testing and oil top-ups on cars, light trucks, and many home or office air-conditioning units.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the injector actually feed oil or dye into my A\/C system?\u003c\/h3\u003e\n\u003cp\u003eThe injector uses a two-cylinder dispensing design: an inner core and outer sleeve screw together to push fluid through a 1\/4\" SAE threaded port into the low-pressure side. A check valve prevents refrigerant or return flow into the injector when disconnected. Follow the simple filling and tightening steps to purge air and meter the amount of oil or dye you introduce.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e2 oz (60 ml) maximum capacity for measured additions\u003c\/li\u003e\n  \u003cli\u003e1\/4\" SAE threaded port with anti-backflow valve\u003c\/li\u003e\n  \u003cli\u003eInner core screw purges trapped air before injection\u003c\/li\u003e\n  \u003cli\u003eCompatible with POE, mineral oils and fluorescent leak dyes\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich couplers and adapters come with the kit, and what systems do they work with?\u003c\/h3\u003e\n\u003cp\u003eThe kit includes low-side quick couplers for R134a and R1234yf plus an R410a mini split adapter so you can connect to a wide range of refrigerant service ports. The R134a coupler is a 1\/4\" SAE male x 13 mm female style, while the R1234yf coupler fits modern 14 mm service ports. The R410a adapter converts a 5\/16\" SAE female to a 1\/4\" SAE male for mini-split systems.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eR134a low-side quick coupler: 1\/4\" SAE male x 13 mm female\u003c\/li\u003e\n  \u003cli\u003eR1234yf low-side coupler: 14 mm female compatible with 13 mm R134a\u003c\/li\u003e\n  \u003cli\u003eR410a mini-split adapter: 5\/16\" female to 1\/4\" male\u003c\/li\u003e\n  \u003cli\u003eIncludes a valve core remover for service port maintenance\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I use the injector safely and avoid system contamination?\u003c\/h3\u003e\n\u003cp\u003eClean handling and the correct dye\/oil type prevent contamination: use dyes designed for the refrigerant oil in your system and keep the kit components clean and capped when not in use.
