How many grades of wall thickness does the soft temper copper tubing have?

Soft temper copper tubing is classified based on its wall thickness into two grades: Type K and Type L. Type K has the thickest wall, while Type L has a thinner wall compared to Type K, making it suitable for various applications depending on structural strength and flexibility requirements. The two grades allow for a range of uses, from high-pressure systems to more general plumbing applications.

This distinction is important for plumbers to understand because it affects the tubing's performance in various scenarios, including its ability to withstand pressure and the ease with which it can be bent or shaped for a particular installation. By recognizing these two grades, a plumbing professional can select the appropriate type of soft temper copper tubing for their specific needs, ensuring both reliability and compliance with building codes and regulations.
