The primary reason recovery cylinders are color-coded gray with a yellow top is to:

Giải thích
The gray body and yellow shoulder identify a container as a recovery cylinder holding used or mixed refrigerant, keeping it visually separate from color-coded virgin refrigerant containers. This reduces the chance of accidentally charging a system with contaminated refrigerant. The color does not indicate empty, flammable, or disposal status.
