What color is Type K copper tube color-coded to distinguish it from other types?

Type K copper tubing is indeed color-coded green to distinguish it from other types of copper tubings, such as Type L and Type M. This color-coding is an important aspect in the identification and appropriate application of the tubing. Type K has the thickest walls among the three types, making it suitable for high-pressure applications, underground installations, or other situations where additional durability is required.

Understanding this coding helps professionals quickly recognize the appropriate type of tubing for the job at hand, ensuring safety and compliance with building codes. It is essential to be familiar with the standards and color codes to avoid mistakes in material selection that could lead to system failures or code violations. The color assigned to Type K serves as a reliable visual guide for anyone working with plumbing or HVAC systems.
