Buying Guide for 3/4 OD Copper Tubing

Understanding Copper Tubing

When I first started working with plumbing and HVAC projects, I quickly learned that copper tubing is a popular choice due to its durability and resistance to corrosion. The 3/4 inch outer diameter (OD) copper tubing is versatile, often used in both residential and commercial applications. It’s essential to understand what this measurement means and how it affects my project.

Types of Copper Tubing

As I explored my options, I discovered there are different types of copper tubing: Type K, L, and M. Type K has the thickest walls and is suitable for underground installations. Type L is a great all-around choice for most plumbing and heating applications, while Type M is thinner and often used for residential water systems. Knowing these types helped me select the best fit for my needs.

Application Considerations

Before purchasing, I considered what I would use the copper tubing for. Whether I was working on a heating system, plumbing, or refrigeration, the application influenced my choice.
