HANSUM 50FT Mini Line Set – 3/8”/5/8” Copper, Insulation

Upgrade your HVAC or heat‑pump system with the HANSUM 50FT Mini Line Set, designed for seamless installation and reliable performance. This kit features twin copper lines—high‑pressure (9.52 mm / 3/8”) and low‑pressure (15.88 mm / 5/8”)—each fully flared for leak‑free connections. The copper ends are finished with precision flare fittings and anti‑cracking thickened nuts, ensuring long‑term durability under varying pressure cycles.

Triple‑layer insulation protects the copper tubing against temperature loss and environmental damage. The kit’s insulation consists of embossed polyethylene film, weather‑resistant foam, and thickened cotton, providing superior thermal efficiency and preventing condensation on the lines. With 50 ft of insulated tubing, the set is ideal for most residential and commercial mini‑split installations. It also includes a 50‑ft drain hose, five insulation straps, a decorative wall cap, and wall filler putty for a complete, ready‑to‑install solution.

Compatible with 9,000‑36,000 BTU mini‑split air conditioners and heat pumps that require 3/8” or 5/8” line sizes, this line set delivers a cost‑effective, high‑quality alternative to OEM parts. The kit’s components are engineered for quick assembly, making it a practical choice for HVAC technicians and DIY installers alike.
