Built for field use, the kit features a quick-snap low-side coupler, 1\/4\" SAE connection, and a 2-ounce push-in cylinder so you can meter lubricant and dye into systems for maintenance, diagnostics, or recovery from low-oil conditions.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the SURIEEN injector add oil or dye without running the compressor?\u003c\/h3\u003e\n\n\u003cp\u003eThe injector uses a precharged inner cylinder and a simple push-turn valve to force oil or dye into the low-pressure side of the system. Because it seals to the low-side service port and relies on manual pressure rather than the running compressor, the tool is safe for adding measured amounts while the system is off.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e2 oz (60 ml) push-type reservoir for controlled dosing\u003c\/li\u003e\n  \u003cli\u003eLow-side 13 mm snap-on coupler for leak-free connection\u003c\/li\u003e\n  \u003cli\u003e1\/4\" SAE threaded fittings for standard compatibility\u003c\/li\u003e\n  \u003cli\u003eCompatibility with POE, mineral oil, and fluorescent dyes\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich refrigeration systems and refrigerants are compatible?\u003c\/h3\u003e\n\n\u003cp\u003eThe injector is built to work with a wide range of systems—automotive and HVAC—using common refrigerants.
