RectorSeal Refrigerant Line Connector for Mini-SplitsRectorSeal NoKink™ is a flexible, non-kinking refrigerant line connector for quick, easy, and more reliable refrigerant lineset connections to wall and ceiling-mounted mini-split evaporators. It eliminates inadvertent kinking, even with sharp 90-degree bends, that potentially lead to leaks on rigid, cumbersome linesets in the typically tight quarters of wall-mounted and ceiling-cassette mini-split evaporator installations.
