In plumbing systems, one of the primary goals is to keep the water or other liquid free from impurities. But, even as you filter off the impurities, there is still a risk of reaction in the plumbing system and releasing harmful molecules of lead into the water. Lead free plumbing fittings are made with brass or steel to reduce the danger of lead contamination. Brass is preferred for hot water fittings
because it is ductile in hot temperatures and easy to work with because of high malleability. Some of the main lead free plumbing components include plumbing nipples that have male threads at each end. Nipples
are used for connecting two other plumbing fittings such as a pipe, hose, and valve. Note that nipples are recommended for low-pressure plumbing. Another common lead free fitting component is the pipe & elbow that helps to change the direction of the pipe. The standard types are designed to change the pipe and flow direction by either 90В°, 60В° or 45В°.
