Coiled copper refrigerant line set with flared ends and insulation

Streamline

Streamline 61020350 Liquid and Suction Line Set 35 ft Copper

SKU CH-3RVE-1XSG0

Copper refrigerant line set with flared ends for mini-split air conditioning and refrigeration systems

  • Product colorTransparent
  • 35 ft length covers long runs between indoor and outdoor units
  • Copper construction resists corrosion and handles high refrigerant pressures
  • 3/8 in liquid and 5/8 in suction lines match common mini-split specifications
  • 1/2 in insulation thickness reduces thermal loss and prevents condensation
  • Pre-flared ends allow quick, leak-tight connections without field flaring tools

Liquid and Suction Line Set for Mini-Split Systems

This copper line set connects the indoor and outdoor units of mini-split air conditioning and refrigeration systems. It comes in a 35-foot length with both liquid and suction lines included. The set is designed for professional HVAC installations where pre-flared copper lines are required.

Pre-Flared Ends and Half-Inch Insulation Speed

Each line terminates in factory-flared ends so no on-site flaring tools or brazing are needed during setup. The 1/2-inch thick insulation wraps both the 3/8-inch O.D. liquid line and the 5/8-inch O.D. suction line to prevent thermal loss and condensation. This ready-to-mount configuration reduces labour time on the job site.

Verify Line Sizes and Run Length Match Your

Confirm that the 3/8-inch liquid and 5/8-inch suction diameters correspond to the manufacturer's piping requirements for your specific mini-split model. Ensure the 35-foot length covers the distance between your indoor and outdoor units without excessive slack or tension. Check local codes for any additional insulation or support mandates.

Questions about this item

How often should the 1/2 inch insulation on the 35 ft copper lines be inspected or replaced?

Inspect the 1/2 inch thick insulation annually for tears, compression or UV damage; replace any compromised sections to maintain thermal efficiency and prevent condensation on the copper tubing.

What pressure or temperature limit is reached first when the line set runs continuously in a mini-split system?

The 3/8 inch O.D. liquid line and 5/8 inch O.D. suction line with flared ends dictate the system's maximum working pressure and temperature ratings; consult the equipment manufacturer's specifications for exact limits.

Does the copper tubing transmit vibration or heat into the living space during all-day operation?

The 1/2 inch insulation on both the 3/8 inch liquid and 5/8 inch suction lines dampens vibration and limits heat transfer; secure lines with insulated clamps to further reduce noise transmission.
