20FT Mini Split Line Set 1/4*3/8 OD HVAC Copper Tube Pipe Extension,3/8 Thickene

About this item

This mini split line set pairs 1/4" and 3/8" OD copper tubing in a 20 ft length. That size combination is common for ductless heat pump and AC extensions. The seller's title notes a thickened 3/8" line, so confirm the wall details in the listing.

Will a 1/4 x 3/8 line set fit my mini split?

Check the service valve sizes on your outdoor unit and the manufacturer's maximum line length. If the ports read 1/4" for the liquid line and 3/8" for the suction line, this set matches.

• Look in the photos for insulation, flare nuts and end caps. The listing data doesn't specify them.
• Torque flare connections to spec and evacuate the system before opening the valves.
• Refrigerant work may require EPA certification and a local permit.
• Your purchase is covered by the eBay Money Back Guarantee.
