The CAMBRIDGE-LEE INDUSTRIES 061208500B is a pre-insulated refrigerant line set designed for field installation in split-system and ductless applications. The set includes a 3/8-inch liquid line and a 3/4-inch suction line, both constructed from copper meeting ASTM B743/B88 material specifications. The suction line is wrapped in 1/2-inch black polyethylene hard-shell insulation rated for UV exposure and approved for use with R-410A refrigerant. At 50 feet in length, this line set is suited for standard residential and light commercial runs. Both ends terminate with plain connections, ready for brazing or flaring by a licensed refrigeration technician.
This line set is engineered for ductless mini-split systems, VRF commercial systems, and conventional split-system air conditioners and heat pumps. The rugged anti-tear exterior simplifies pulling the line set through tight spaces, wall penetrations, and conduit during installation. The insulation is marked every foot along its length, allowing technicians to measure and cut accurately on the job without a separate tape measure. It suits both new construction and retrofit scenarios where a pre-paired line set reduces staging time.
Designed for use with ductless mini-split systems, VRF commercial systems, and split-system air conditioners and heat pumps. Suitable for R-410A refrigerant systems.
Installation should be performed by an EPA 608-certified HVAC technician. Shut down and recover all refrigerant from the system before disconnecting or modifying any refrigerant lines. Connections are plain-end style and require proper brazing or flaring technique using tools appropriate for ACR copper tubing. Support the line set at regular intervals per local mechanical code requirements to prevent sagging or vibration damage over the run.
