Cambridge-lee Industries DL06100850BX Mini-split Line Set

Product Description

The CAMBRIDGE-LEE INDUSTRIES DL06100850BX is a pre-insulated copper mini-split line set designed for residential and light commercial ductless HVAC installations. The set includes a 3/8-inch liquid line and a 5/8-inch suction line, both wrapped in 1/2-inch black polyethylene hard shell insulation for thermal protection and UV resistance. At 50 feet in length, this line set suits a wide range of single-zone mini-split installations where the indoor and outdoor units are separated by a moderate run. Both ends are plain, allowing the installing technician to field-flare or braze connections to match system requirements. Copper construction meets ASTM E9600 material specifications.

This line set is intended for HVAC mini-split system installations, covering both new construction and replacement service work. The 50-foot run accommodates typical wall-mount or ceiling-cassette indoor units paired with outdoor condensing units. The hard shell polyethylene insulation jacket protects the suction line from heat gain and condensation, maintaining system efficiency. Licensed HVAC technicians performing lineset installation in residential single-family homes, condominiums, and small commercial spaces will find this a direct-pull, ready-to-run option that minimizes field prep time.

Compatibility

Designed as an OEM-style replacement or new-installation line set for residential and light commercial ductless mini-split systems requiring a 3/8-inch liquid line and 5/8-inch suction line configuration.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with local mechanical codes and the equipment manufacturer guidelines. Power down and disconnect the outdoor condensing unit before connecting or disconnecting any refrigerant lines. Plain ends require proper field flaring or brazing before system evacuation and charge; ensure all joints are leak-checked before system startup. Secure the line set at appropriate intervals to prevent vibration contact with structural surfaces.
