Type L copper tube has which color stripe?

Type L copper tube is designated by a blue stripe. This color coding is important for identifying the type of copper tubing used in various plumbing applications. Type L copper tubing has thicker walls compared to Type M, making it suitable for a variety of plumbing systems, particularly where higher pressures may be encountered.

The blue stripe indicates this specific type, helping pipefitters and plumbers quickly recognize the appropriate material for a given job. Identifying the correct type of copper tube is critical, as it ensures compliance with building codes and standards, as well as the longevity and safety of the plumbing systems being installed or repaired.

In contrast, other types of tubing with different stripe colors serve different purposes or applications, highlighting the importance of understanding the color-coding system in the plumbing trade.
