What is 1/8 inch copper refrigeration tubing used for?

Tube this small is often used for pressure sensing lines, gauge and instrument connections, and capillary-style runs on refrigeration equipment. It isn't a size used for household water lines.

• It's sized by outside diameter. Match flare nuts, compression fittings or braze joints to 1/8" OD.
• Open box: check the photos for kinks and whether the ends are still capped.
• Confirm the wall thickness and whether it's coiled in the listing details.
• Use a small tube cutter and bender so you don't crush the tube.
