FlareSeal MSP-0610 addresses vibration, surface scratches, minor misalignment and debris by adding a multi-ring copper sealing element that is fully coated to improve conformity and durability. This product ships as a mini-split pack containing two 3\/8\" and two 5\/8\" seals, sized for typical liquid and suction lines found on larger ductless units.\u003c\/p\u003e\n\n\u003ch3\u003eHow does FlareSeal stop leaks at flare connections?\u003c\/h3\u003e\n\u003cp\u003eThe MSP-0610 uses an engineered multi-ring copper face that compresses into the mating flare to form a tight, crush-style seal.
