Cambridge Mini Split Accessories

Overview

The CAMBRIDGE 222790 is a pre-insulated mini split lineset designed to connect the indoor air handler to the outdoor condensing unit in a ductless mini split system. This lineset features a 1/4-inch liquid line and a 3/8-inch suction line, spanning 35 feet to accommodate a wide range of installation distances. It ships with double flare nuts and does not include communication wire, making it suited for systems that use separate wiring or wireless communication.
