25ft Line Set Kit

Get a clean, professional mini-split installation without piecing parts together. The AR 25 ft Line Set Kit includes insulated copper lines plus all core accessories needed to connect your indoor unit to your outdoor condenser—everything in one box.

Built for 9K–12K mini-split systems, this longer 25 ft run gives you flexibility for more complex installs where 16 ft isn’t enough.

What’s Included in the Box

• 25 ft insulated copper line set (1/4″ liquid + 3/8″ suction)
• 16.4 ft PVC corrugated drain hose
• 29.5 ft communication cable
• 2 cable ties
• Through-wall sleeve + wall cover
• Sealing mud for weatherproof penetration

Key Features

✅ Correct Size for 9K–12K Systems

1/4″ liquid line + 3/8″ suction line—standard sizing for most small residential mini-splits.

✅ 25 ft Length = More Flexibility

Perfect for installs where the condenser isn’t right outside the wall. Ideal for homes, garages, and longer routing paths.

✅ Factory-Flared Connections

Pre-flared ends help ensure a tight, leak-resistant seal and faster installation.

✅ Complete Kit 

Includes all parts needed: drain hose, wiring, wall hardware, and sealing materials. No last-minute trips to finish the job.

✅ Clean, Professional Result

Everything is designed to route neatly through the wall and protect the install from weather exposure.
