A.y. Mcdonald 5420-467 Ball Valve 1/2 Inch Fpt Lead Free

Product Description

The A.Y. MCDONALD 5420-467 is a lead free, full port ball valve designed for shut-off and flow control in potable water and general plumbing systems. At 1/2 inch with female pipe thread (FPT) connections on both ends, this valve delivers unrestricted flow when open, minimizing pressure drop across the fitting. The lead free construction meets federal and state safe drinking water requirements, making it suitable for installation on domestic water lines. Plumbers and pipefitters install this valve in residential and light commercial applications where reliable manual isolation is required.

This valve is well suited for use on cold and hot water supply lines, branch connections, and service shutoffs in residential construction and retrofit plumbing work. The full port design is preferred in systems where maintaining full line velocity matters, such as recirculation loops and supply feeds to fixtures and equipment. Its compact size and threaded end connections make it a straightforward swap in tight spaces.

Key Features

• Lead free construction meets federal Safe Drinking Water Act requirements for potable water service
• Full port bore maintains full line flow with minimal pressure drop
• 1/2 inch FPT connections on both ends for standard threaded pipe assembly

Compatibility

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve system pressure before removing any existing valve or fitting. Apply thread sealant tape or compound to male threads before making up the connection. Do not over-tighten threaded joints, as this can crack valve bodies or fittings.
