The ICOOL f385812050 is a 50-foot, rubber-insulated copper line set designed for mini split air conditioning systems and refrigeration applications. It ships as a matched pair of suction and liquid lines — 3/8 inch and 5/8 inch outside diameter — wrapped in 1/2 inch thick rubber insulation. The insulation is rated for a temperature range of -58 to 230 degrees F, making it suitable for both chilled refrigerant and medium-temperature hot fluid service. Licensed HVAC technicians install this line set when connecting an outdoor condensing unit to an indoor air handler in residential or light commercial mini split installations.
This line set is appropriate for mini split systems in both residential and light commercial settings. It is rated for buried and above-ground installations. The manufacturer recommends installation on non-operational systems with clean, dry surfaces in ambient temperatures between 40 and 100 degrees F. The rubber insulation resists UV exposure and chemical contact, making it a practical choice for exposed exterior runs as well as concealed routing through walls or conduit.
Designed for use with mini split systems requiring a 3/8 inch liquid line and 5/8 inch suction line. Suitable for chilled water, refrigeration, hot water plumbing, solar thermal piping, and liquid heating applications. Approved for buried and above-ground installations.
Installation should be performed by a licensed HVAC technician familiar with refrigerant piping practices and local mechanical codes. Ensure the system is de-pressurized and power is disconnected before connecting or modifying line set ends. Plain end copper tubing requires field flaring or the use of appropriate fittings — use a calibrated flaring tool and inspect each flare before making connections. Install only on clean, dry surfaces with ambient temperatures between 40 and 100 degrees F as specified by the manufacturer.
