Bostome 50FT Mini Split Line Set – 3/8" & 5/8" Copper Pipes with Triple Insulation

Before: You’re on the job at 2 p.m., attic temp climbing, and the last mini-split line set kinked under the joists—now you’re cutting couplings, chasing leaks, and explaining delays to a homeowner who just wants cool air.

After: One pull of Bostome 50ft copper spans the width of the house, bends without flattening, and the WATERPROOF triple insulation keeps suction lines sweat-free so the system hits rated SEER and your customer smiles instead of asking questions.

Bridge: The Bostome 50ft Mini Split line set is the bridge between lost hours and a same-day finish. ASTM-grade 3/8” + 5/8” copper pair with extra-thick walls resists crush and corrosion; pre-flared, color-coded ends and two cinch straps let you flare, connect, vacuum, and go—no special tools, no extra joints to leak. Rated 18–26 k BTU, it matches most single-zone units for bedrooms, garages, or office add-ons. Add it to cart now, finish before lunch, and move on to the next job with sealed, season-long comfort.
