This line set is a complete pre-insulated copper refrigerant lineset for ductless mini split installations. Featuring a 1/4" liquid line paired with a 5/8" suction line, both wrapped in 1/2" insulation, this 15 ft set provides DMS Flared connections that eliminate the need for on-site flaring — saving installation time and providing a cleaner, leak-resistant joint. Built to ASTM standards and engineered to work seamlessly with Daikin Entra, Oterra, Aurora, Atmosphera, and multi-zone systems.
