I also pay attention to whether it is soft, hard, or annealed copper, since that affects how easy it is to bend and install.

Why Copper Tubing Matters to Me

I like copper tubing because it is durable, resists corrosion, and handles heat well. In my experience, it is a reliable choice for long-term use. I also appreciate that copper has strong conductivity, which makes it useful in systems where heat transfer matters.

Things I Check Before Buying

Before I buy, I look at a few important details:

  • Wall thickness

  • Whether it is suitable for indoor or outdoor use

I find that these details help me avoid buying tubing that does not fit my project.

Soft vs. Hard Copper Tubing

I always decide between soft and hard tubing based on the job. Soft copper is easier for me to bend and shape, so I prefer it for projects with curves or tight spaces. Hard copper feels better for straight runs because it is more rigid and holds its shape well.

Installation Tips I Follow

When I install copper tubing, I handle it carefully to avoid bending or crushing it. I use the right cutter and fittings, and I always double-check measurements before making a cut. If soldering is needed, I make sure the surfaces are clean and properly prepared.

My Final Buying Advice

My best advice is to buy 7/8 copper tubing only after confirming the size, type, and application. I have found that choosing the right grade and wall thickness saves time and prevents problems later. If I focus on quality and compatibility from the start, I usually get better results from the project.
