A.Y. McDonald 5180-012 Compression x MNPT Adapter, No Lead
The A.Y. McDonald 5180-012 (cross-referenced to manufacturer part 74753-67) is a 5/8" x 3/4" compression x MNPT adapter engineered to transition from a compression connection on 5/8" tubing to a 3/4" male NPT threaded outlet. Manufactured to No Lead (NL) standards, this adapter is well suited for potable water service line and plumbing connections where lead-free construction is required by code. The compression end accepts 5/8" tubing (XS) while the opposite end terminates in a 3/4" male NPT thread, allowing a secure, code-compliant transition between tubing and threaded pipe, valves, meters, or other threaded components. This dual-format design makes it a practical, dependable choice for water utility and plumbing professionals who need a reliable, gasket-free mechanical seal at the tubing connection paired with a standard threaded outlet.
