The right-sized connection for smaller mini split systems. The Aervan 25 Ft Mini Split Line Set combines a 1/4 in high-pressure line and a 3/8 in low-pressure line in pure copper, the size most commonly used on compact ductless units.

Triple-layer insulation (polyethylene film, heat-resistant foam and cotton) keeps refrigerant temperatures stable and prevents dripping condensation, and the M1 flame-retardant rating and ASTM-compliant copper give you peace of mind. It stays flexible in weather down to -40 °F.

Why you'll love it

  • Pure copper – 1/4 in and 3/8 in O.D. pipes for efficient heat transfer.
  • Triple-layer insulation – minimizes condensation and energy loss.
  • M1 flame-retardant – ASTM-compliant copper.
  • All-weather – resilient down to -40 °F.
  • Easy to install – cut-and-solder design; 2 protective caps included.
  • Universal compatibility – fits most split AC and heat pump units using 1/4 × 3/8 in lines.

Perfect for: installing or extending smaller ductless mini split and heat pump systems.
