16FT Mini Split Line Set 1/4*3/8 OD HVAC Copper Tube Pipe Extension,3/8 Thickene

About this item

Short ductless installs often don't need a long coil. This 16-foot mini split line set pairs 1/4 inch and 3/8 inch OD copper tubes for HVAC runs and extensions. It is listed as new, and the title calls it thickened.

• Sizes: 1/4 x 3/8 is a common line combination on smaller mini split heads, but your unit's manual is the final word.
• Thickened: the title is cut off, so check whether this refers to the insulation or the copper wall.
• Ends: look for pre-flared ends with nuts in the photos, or plan to flare them yourself.
• Length: 16 feet suits a back-to-back wall install or a short outdoor run.

Can I install a 1/4 x 3/8 mini split line set myself?

You can route the copper yourself. Vacuum, leak testing and refrigerant work usually require a certified tech, and permits vary by area.
