Quickun Copper Tube 3/16" ID × 1/4" OD (5-6.35mm) Seamless Round Pipe Tubing (3.28FT)

I received the Quickun Copper Tube 1/4" ID × 5/16" OD Seamless Round Pipe Tubing (3.28 ft) and overall it performs as expected for small fabrication, HVAC, or DIY repair projects. The tubing arrived straight, clean, and free from visible dents or kinks, which is important if you're planning to use it for fluid or refrigeration applications. The copper feels solid and uniform, and it cuts and flares without excessive cracking when using standard tubing tools. The seamless construction is a plus because it helps with durability and reduces the likelihood of leaks when properly installed. I also found it easy to bend carefully using a tubing bender without collapsing the pipe walls. One thing to keep in mind is that this is a relatively short length at just over 3 feet, so depending on your project you may need to purchase multiple pieces. Also, like most soft copper tubing, you’ll want to handle and store it carefully to avoid accidental deformation. Overall, this is a good quality copper tube that should work well for hobbyists, repair technicians, or light professional use. It appears to be accurately sized and well manufactured for the price point.

Met the specifications for my job. Works great

This length of copper tubing is about a yard long and is adequate for most needs such as splicing damaged line. I noticed that the specifications seemed to indicate that wall thickness was .001" thinner than normal nominal tubing of the size, but working with it i could not tell a difference. I used it to splice an old copper line and it worked fine.

This is an excellent product easily bendable and great a application home Distillery

It’s not 3/16, it’s 5mm copper tubing, don’t buy

Good product. Good service.

as described

I needed to run some new tubing while working on an air compressor, and this worked perfectly. It's uniformly round without any abnormalities, and easy enough to bend. I used a cheap, little tubing bender and all my bends came out just fine without kinking. I used some silver solder to secure the fittings, and they bonded with no issues. Overall, I'm quite pleased.
