What color stripe indicates type "K" hard-drawn copper tubing?

Type "K" hard-drawn copper tubing is indicated by a green stripe along its exterior. The color coding system for copper tubing is crucial for identifying different types, as each type has specific characteristics and applications. Type "K" tubing is known for its thicker walls and is commonly used in applications where higher durability and pressure resistance are required, such as in underground or heavy-duty systems.

Different colors signify various types of copper tubing: for instance, Type "L" is denoted by a blue stripe, indicating it has a medium wall thickness, and Type "M" has a red stripe for its thinner walls, which are typically used in less demanding applications. Understanding these color codes is essential for ensuring proper selection and installation in plumbing systems.
