3/8" Seamless Copper Refrigeration Tubing - 50ft Coil for HVAC & Line Set

About this item

Liquid lines on most home split systems use small-diameter tube, and 3/8 inch seamless copper refrigeration tubing is a common choice. This 50 ft coil is listed new for HVAC and line set work by an independent eBay seller.

Does 3/8" refrigeration tubing work for a mini-split line set?

It can, if your unit's liquid or suction connection is 3/8" OD. Check the install manual for both line sizes. You'll usually need a larger tube for the second line.

• Size: 3/8", 50 ft coil.
• Construction: seamless, according to the title.
• Joining: flare for many mini-splits, brazing for most other systems.
• Check: the title doesn't mention wall thickness or insulation, so read the listing.
