It reduces friction, improves cooling efficiency, and includes a fluorescent UV dye for easy leak detection. Compatible with condensers, hoses, evaporators, gaskets, and O-rings, it extends system life while optimizing fuel and refrigerant use. Requires a can tape valve (included) for application. ## Description RACO Sigma A/C stop leak will permanently stop leaks in condenser, connection hoses, evaporators, gaskets, and O-rings in systems that can hold 5 inches of vacuum for 25 minutes. It is not recommended for systems that lose more than 1 pound of freon per day or leaking compressors. It is 100%safe for all A/C systems, and will not damage the orifice tubes of recovery equipment. Direction 1. Turn the sliver twist valve all the way in a clockwise direction. 2. Shake can well. 3. Attach the delivery system to the can by screwing the red adapter to the top of the can puncturing the protective film. 4. Start the car and turn A/C to max cooling. 5. Attach the quick coupler to the low-side service port. 6. Once the quick coupler is attached check guage for accurate pressure reading. See table to compete outside temperature to sufficient pressure in the system. If guage reading shows deficient pressure, slowly turn to twist the valve counterclockwise to release the product. 7. Hold the can in an upright position and gently shake it every 5 seconds while the system is being charged. It should take 5-12 minutes for the can to be empty. 8. Check guage throughout the process to measure psl. Guage reading is only accurate when the compressor is cycling. Do not overcharge！ If system pressure is still low, add more r134a. Review: Zero star - The valve that comes with the can doesn't attach to it. It's completely useless and a waste of time and money!
