Couplings are among the most common copper fitting types and are used to connect (2) equal size or different size copper pipes in a straight line. They come is equal or reducing types. These copper couplings feature a rolled stop, which prevents the pipe from sliding past the center of the coupling.
Material used for producing these fittings is a C12200 alloy, also used by leading US copper fitting manufacturers, including Nibco, Mueller and others.
These copper couplings are NSF certified for use in drinking water applications, lead-free compliant and UPC listed.
