What color is the "no lead" label found on certain plumbing fittings?

The "no lead" label on certain plumbing fittings is green. This color is standardized to indicate that the fittings comply with regulations regarding lead content, specifically those set forth by the Safe Drinking Water Act. The green labeling helps ensure that plumbers and consumers can easily identify products that are safe for use in potable water systems, thereby reducing the risk of lead contamination. The green label serves not only as a compliance marker but also raises awareness among professionals about the importance of using lead-free materials in plumbing installations. This is crucial in maintaining public health, particularly in systems that supply drinking water.
