The rise of lead-free brass alloys was driven by increasing awareness of the dangers of lead contamination in drinking water, especially in the aftermath of incidents like the water crisis in Flint, Michigan. To address these concerns, regulatory bodies such as the U.S. Environmental Protection Agency (EPA) and the National Sanitation Foundation (NSF) introduced stricter regulations on the materials used in plumbing systems. Lead-free brass, made from copper and zinc with minimal lead content, has become the standard for plumbing fittings in today's market.

In terms of design, modern brass fittings manufacturer are manufactured using advanced casting, forging, and machining techniques that ensure consistency, precision, and reliability. Computer-aided design (CAD) and computer numerical control (CNC) machines have enabled manufacturers to produce complex fittings with greater accuracy, a reduction in installation errors and an increase in system efficiency.
