Mueller Streamline a02547nl Male Adapter C X Mpt 3/4 Inches X 1-1/4 Inches Lead-free Cast Brass

Product Description

The MUELLER STREAMLINE a02547nl is a lead-free cast brass male adapter designed for connecting copper solder-joint pipe to male pipe tapered thread (NPT) fittings. One end features a 3/4 inch cup (female solder) connection, and the other end is a 1-1/4 inch male pipe tapered thread (MPT/NPT) outlet. This combination makes it a reliable transition fitting used in drain, waste, and vent (DWV) plumbing systems as well as a variety of other sanitary piping applications where a copper-to-threaded transition is needed. Plumbers and pipefitters rely on this type of adapter when converting between soldered copper lines and threaded pipe connections in residential, commercial, and light industrial plumbing work. The fitting is constructed from a high-grade lead-free cast brass alloy, meeting modern plumbing codes and health safety requirements for potable water and sanitary systems. Its robust brass construction resists corrosion and provides long-term durability in both wet and dry environments. The cup end accepts standard 3/4 inch copper pipe and is soldered using conventional techniques, while the 1-1/4 inch MPT end threads directly into female-threaded fittings, valves, or fixtures. This adapter meets multiple ASME standards including B16.15, B16.18, B16.22, B16.24, B16.50, and B1.20.1, ensuring dimensional accuracy and compatibility across standard copper fitting systems. Weighing just 0.38 pounds, the a02547nl is easy to handle and install in tight spaces. It is a trusted component in professional plumbing repair, renovation, and new construction projects requiring a reliable C x MPT transition.
