Full description
Tap to expand
Armbridge bundled installation kits are built to make ductless mini split installs faster and more consistent. Each kit combines a pre-flared, pre-insulated copper line set with communication cable, drain hose, and accessories, so technicians can arrive on site with everything needed for a clean, professional install.
The copper line set uses 99.9% copper (ASTM B-280) and factory-applied insulation (ASTM D154) with UV and UV-C protection, helping it stand up to attic, crawlspace, and exterior runs. Pre-flared ends reduce on-site prep time and help support reliable connections when installed to manufacturer torque specs.
Included 4/16 AWG connecting cable, rubber drain hose, bandage tape, wall sleeve, and neoprene components help simplify penetrations and routing, giving the finished job a more polished appearance while protecting lines from abrasion and weather.
