Cambridge 223525 Mini Split Line Set 3/8x5/8in 50ft

Product Description

The CAMBRIDGE 223525 is a pre-insulated mini split line set designed to connect the indoor air handler to the outdoor condensing unit in ductless mini split systems. This line set features a 3/8-inch suction line and a 5/8-inch liquid line, spans 50 feet, and includes double flare nuts on both ends for secure, leak-resistant connections. The tubing is wrapped in Armashield insulation to protect against thermal loss and condensation. This is a no-wire configuration, making it suited for installations where low-voltage communication wire is run separately or is not required. Licensed HVAC technicians and refrigeration mechanics handle installation.

This line set is used in residential and light commercial ductless mini split applications where the indoor and outdoor units are separated by up to 50 feet. The 3/8 x 5/8-inch line size is a common pairing for single-zone mini split systems in the 9,000 to 24,000 BTU/h range. The included double flare nuts allow for direct connection to standard service valves without additional fittings in most installations.

Installation Notes

Installation of mini split line sets must be performed by a licensed HVAC technician or EPA Section 608-certified refrigeration mechanic. Power down and disconnect the outdoor condensing unit before making any refrigerant-side connections. Verify that all double flare connections are tight and leak-free before pulling a vacuum and charging the system. Secure and protect the line set run from physical damage per local mechanical codes.
