1/2"(13mm) OD 99.9% Copper Tube 0.5mm Wall × 300mm Length × 4Pcs, Pure Copper Tubing 110 Copper Seamless Round Tubing for Refrigerator, Jewellery and Industry

This copper tube was perfect for the job. I am working on some pool stuff and this was just what I needed.

It's copper. It's good copper. It's expensive copper.

The seller wraps the copper in foam casing that keeps the copper nice and polished looking. The baggies the copper is then places in are labeled to help keep up with the sizes which is nice since I use various sizes for my projects. Very professional and fast.

5 stars if the size was accurate. the 5/8" tube is really 16mm, making it impossible to fit a flaring tool.

Anyone into Speaker building forget tube connectors. These are the deal. These fit a standard banana plug. Absolutely perfect. Nothing like a pure copper transfer from the back of the amplifier straight to your crossoversWith the 5 mm drillbit, these things press in really snug, just solder your hook up wire to the inside end , you can do 6 sets of speakers for about $8 depending on how long you cut them

Needed a small section for a shower installation. The diameter was correct and worked as intended.

We needed a nice looking piece of copper pipe to finish off our recirculating fountain. With much searching we came across this item. It is attractive, has no burrs, and has an inside diameter perfect for 5/8” od pvc tubing.

Working with AC. Found this size copper pipe is not carried at the local big box store. AC measures the copper differently than "water" copper. This fits a ¾ AC copper.
