It’s a one-person tool intended for quick diagnostic or maintenance tasks where you want controlled metering of up to 1 oz (30 ml) per push, and it eliminates the need to use the system compressor during the injection procedure.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I connect the injector to my vehicle or HVAC low-side port?\u003c\/h3\u003e\n\u003cp\u003eAttach the appropriate quick coupler for your refrigerant type, then screw the injector onto the low-side service port. The kit includes R134a and R1234yf couplers and a mini split R410a adapter so you can match common service ports without extra tools.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eUse the 13mm R134a low-side quick coupler for most automotive systems.\u003c\/li\u003e\n  \u003cli\u003eSwap to the 14mm R1234yf coupler if your vehicle uses that refrigerant.\u003c\/li\u003e\n  \u003cli\u003eEmploy the R410A mini split adapter for compatible HVAC units.\u003c\/li\u003e\n  \u003cli\u003eUse the included valve-core tool to depress the core and gain access safely.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow much oil or dye can I inject and how precise is the control?\u003c\/h3\u003e\n\u003cp\u003eThe hand-turn screw injector holds roughly 1 oz (30 ml) and dispenses in small, controlled increments when you twist the handle.
