What is the color code for type K copper tubing?

• A. Red
• B. Blue
• C. Green
• D. Yellow

Answer: (C)

Type K copper tubing is identified by a green color code. This type of tubing is the thickest among the commonly used copper tubing types, making it suitable for underground installation or where higher pressure resistance is required. The green color code serves as a quick visual identifier, helping professionals distinguish it from other types, such as Type L (blue) and Type M (red), which have different wall thicknesses and applications. Understanding the color coding for various types of copper tubing is essential for proper material selection in plumbing and gas fitting, as using the correct type ensures safety and compliance with local codes. Correct identification ensures that the right mechanics are applied for installation and usage, contributing to the integrity and reliability of gas systems. The other color codes correspond to different types of copper tubing, each denoting specific applications and requirements.
