50 ft Mini Split Line Set

The VEVOR JSY-SS-SKU2 supplies a 50 ft copper line set with 1/4 in and 3/8 in outer diameters. It is built for installers connecting indoor and outdoor units on mini-split air conditioning or heat pump systems up to 12000 BTU. Thickened pure copper meets ASTM standards for wall thickness, reducing the risk of flattening during bending. Wrapping strips are included for securing the run.

Triple-layer insulation and pressure resistance

Three layers of insulation cotton wrap both tubes tightly, providing thermal protection while remaining waterproof and pressure-resistant. The copper tubing maintains effective insulation across the 50 ft length during normal refrigerant circulation. Net weight of the complete kit is 11.02 lb, and overall packaged dimensions are 20.27 x 20.27 x 6.3 in.

1/4 in and 3/8 in O.D. for 0-12000 BTU systems

The set includes a 1/4 in high-pressure tube and a 3/8 in low-pressure tube, specifically matched to 0-12000 BTU mini-split equipment. Builders needing larger diameters or a different length for higher-capacity units will need a different line set. Length is 15240 mm and tube outer diameters are 6.35 mm and 9.53 mm.

Questions about this item

How do I install the 50ft 1/4" and 3/8" copper tubes without kinking them?

Uncoil the tubing slowly and bend with a tubing bender or spring; the ASTM-grade wall thickness resists flattening but sharp hand bends still cause kinks.

Will the triple-layer insulation cotton need replacement over time?

The three-layer wrap is waterproof and pressure-resistant for the system life; inspect annually for UV damage or tears and tape any breaches with the supplied wrapping strips.

At what BTU limit does the 1/4" high-pressure line become restrictive?

The set is rated for 0-12000 BTU mini-split units; exceeding that capacity increases pressure drop and reduces cooling efficiency.
