The NABCO PZ1013LF adapter is a plumbing fitting designed to connect 3/4-inch PEX tubing to a 1/2-inch Male Pipe Thread (MPT) connection. Constructed from lead-free brass, it provides a secure and leak-free transition between PEX and traditional threaded piping systems. This adapter is suitable for various applications, including potable water systems, hydronic heating, and other residential, commercial, and industrial plumbing installations. The PEX end is typically installed using a crimp connection, while the MPT end features external threads for secure attachment to corresponding female threaded components. Many similar lead-free brass PEX fittings are NSF-certified for safe use in drinking water systems and comply with ASTM F1807 standards for PEX crimp connections.
