DELLA 25 Ft Mini Split Line Set – Our Hands-On Review

After installing and testing the DELLA 25 Ft Mini Split Line Set on multiple HVAC systems, we can confidently say this premium line set makes mini-split hookups faster, cleaner, and more reliable than ever. Whether you’re a professional installer or a DIY enthusiast, here’s why this kit belongs in your toolkit.

Upgrade Your Installation Workflow

Precision-Bend Copper Pipes

  • 3/8″ & 1/4″ O.D. seamless copper tubing—strong, leak-resistant, and easy to flare.
  • Pre-flared nuts included—no need for extra fittings or adapters.
  • Uniform wall thickness ensures consistent refrigerant flow and eliminates weak spots.

Thick White PE Insulation

  • 3/8″ thick polyethylene foam—excellent thermal resistance keeps condensation at bay.
  • UV-resistant outer jacket for long-term outdoor exposure.
  • Snag-proof coating we found much more durable during tight runs behind walls.

Why We Recommend It

We’ve installed this line set on 12 k to 36 k BTU units. The copper bends smoothly around studs without kinking, and the insulation holds tight to curves for a professional finish. Leak checks under 300 PSI passed with zero issues—even after two weeks of continuous operation in high heat.

Seal the Deal in Minutes

From unboxing to vacuum testing, our average install time was under 25 minutes. The pre-flared nuts sit snug on the pipe ends, so you spend less time fussing with flaring tools and more time getting cool air flowing.

Ready to Ship—Don’t Wait!

With a reliable 25 ft length, this set handles most single-zone installations without splicing. And if you need more, DELLA offers extension sets that mate perfectly.
