The 5550 line set is an essential component for connecting the indoor evaporator coil to the outdoor condenser unit in various HVAC/R systems. This specific configuration, featuring 7/8"NPS and 1/2"IN pipe diameters over a 300-foot length, is crucial for establishing the refrigerant circuit. Proper sizing and installation are paramount to maintain system efficiency and prevent issues like pressure drops or inadequate cooling/heating.
This line set is suitable for new installations or replacements in residential and light commercial HVAC applications, including central air conditioning and heat pump systems. Its substantial 300-foot length offers flexibility for installations where indoor and outdoor units are significantly separated, reducing the need for additional brazing and potential leak points.
Ideal for HVAC contractors and installers, this product addresses the need for reliable refrigerant lines for larger or more distant system components. When selecting, professionals should verify compatibility with the specific tonnage and refrigerant type of the HVAC equipment to ensure seamless integration and long-term operational integrity.
