A.Y. McDonald 5122 1-1/2" Lead-Free Flare x FIP Adapter

A.Y. McDonald 5122 1-1/2" Lead-Free Flare x FIP Adapter

The A.Y. McDonald 5122 is a 1-1/2" 503 Flare x FIP (Female Iron Pipe) adapter engineered for reliable transitions between flared tubing connections and threaded pipe systems. Manufactured as a lead-free (LF) fitting, this adapter is designed for potable water and general piping applications where a secure, code-compliant connection is required. The 503-series flare connection design provides a dependable mechanical joint on one end, while the FIP threading allows straightforward assembly to standard iron pipe or fittings on the opposing end, making the 5122 a versatile transition component for water service, distribution, and general plumbing and utility installations. Installers working on new construction or retrofit water service lines can rely on this adapter to bridge dissimilar connection types without introducing additional couplings or complexity into the run.

Key Features

• Trade Size: 1-1/2" nominal size for standard water service and distribution line applications.
