A.y. Mcdonald 5122-147 Flared Coupling 1.5 in

Product Description

The A.Y. McDonald 5122-147 is a no-lead, three-part flared coupling designed for use in potable water and plumbing distribution systems. The three-part construction allows the coupling to be disassembled and reassembled without cutting pipe, making it a practical choice for field repairs and tight-access installations. At 1.5 inches fitting size and weighing 4.95 pounds, this is a robust, full-size coupling suited for licensed plumbers working on residential and light commercial water service lines. No-lead compliance meets federal and state requirements for fittings used in drinking water applications.

This coupling is typically installed on copper tubing in water supply and distribution lines where a serviceable, pressure-rated mechanical connection is required. The flared joint design provides a reliable seal without soldering, making it suitable for retrofit work, meter sets, and service connections where an inspectable, removable joint is preferred. Licensed plumbers and water service contractors are the primary installers of this fitting.

Key Features

• No-lead construction compliant with federal potable water fitting requirements
• Three-part design allows disassembly without cutting or destroying the fitting
• 1.5 inch fitting size for full-bore water service connections
• Flared joint connection provides a mechanical seal without soldering

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1.5 inch flared copper tubing connections in potable water supply and distribution systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve system pressure before disassembling or installing the coupling. Ensure mating tubing ends are properly flared to the correct angle before assembly to achieve a leak-free joint. Do not overtighten the flare nut, as this can distort the flare seat and cause leaks.
