Review on 🔒 FlareSeal MSP-0406: Leak-Free SAE Flare Connections for Refrigerant Leaks in Refrigeration, HVAC, Ductless, Schrader Valve, or Mini Split Applications (1/4" - Mini Split Pack: (2) 1/4" and (2) 3/8") by Eduardo Long

I installed a mini split air conditioner and it was very simple: I cut a long set of copper tubing and flared the end of the copper tubing with a flare/swage kit. When the AC guys came to vacuum the lines and check for leaks, they told me I had a small leak. I received and installed this kit and no more leaks immediately! It was child's play. It's 73 degrees in my solarium and 98 degrees outside. This kit saved me money and a headache!
