What is the color code for Type M copper tubing?

Type M copper tubing is identified by its red color code. This specification is established by the Copper Development Association and is widely used in plumbing and heating applications. The red color signifies that Type M copper tubing has thinner walls compared to other types such as Type L (which is blue) and Type K (which is green), making it suitable for specific uses where lower pressure is encountered, such as in residential water systems.

By using the red color code, professionals can easily identify the tubing's type and ensure they are selecting the appropriate material for their plumbing system requirements, adhering to codes and standards. This identification system helps maintain safety and efficiency in plumbing installations.
