Metal Content of Brass Fittings


Couplings Company brass fittings contain between 2.5-3.7% lead, depending on the type (see below). The U.S. EPA Office of Water Management’s document # EPA-5709/-89-BBB, dated 8/1988, has defined "“lead free"” brass fittings as those that contain NOT MORE THAN 8% lead by weight. As regards the European Parliament and the Council of the European Union citation 2002/95/EC, the “Restriction of Hazardous Substances” Directive (commonly known as RoHS), found in the Official Journal of the European Union dated 13 November 2003 (see “Applications of lead, mercury, cadmium, and hexavelant chromium, which are exempted from the requirements of Article 4”), line 6 states “…lead by weight and as a copper alloy containing up to 4% lead by weight.”

As all Couplings Company brass fittings fall below the U.S. 8% and RoHS 4% standards, they fall within the necessary required guidelines.
