Cerro Mini Split Accessories

Overview

The CERRO 406-2-50 is a pre-insulated mini split lineset designed for use in ductless HVAC system installations. It includes both a 1/4 inch liquid line and a 3/8 inch suction line, each insulated with 1/2 inch wall insulation to minimize heat gain and condensation along the refrigerant circuit. The tubing is plain end, meaning field flaring is required at both connections. At 50 feet in length, this lineset suits installations where the indoor air handler is mounted at a moderate distance from the outdoor condensing unit. HVAC technicians working on residential or light commercial ductless systems will find this a direct-use component requiring no additional insulation materials for a standard run. This lineset is used in ductless mini split system installations where the indoor evaporator unit and outdoor condensing unit require a refrigerant circuit connection. The 50-foot length accommodates wall penetrations, vertical drops, and horizontal runs common in residential installations. Plain end tubing requires the technician to flare each line end on site to match the service port fittings on both the indoor and outdoor units. Both lines arrive fully insulated, reducing field labor associated with sleeving individual copper lines after routing.
