A.y. Mcdonald 5424-017 Ball Valve 4 Inch Fpt Lead Free

Product Description

The A.Y. MCDONALD 5424-017 is a lead free, full port ball valve with 4-inch female pipe thread (FPT) connections. Full port design means the valve bore matches the pipe inside diameter, delivering unrestricted flow with minimal pressure drop across the valve. At 15.73 pounds, this is a substantial brass or bronze-grade fitting intended for demanding commercial and industrial plumbing systems. Licensed plumbers and pipefitters specify lead free valves wherever potable water service or local code compliance requires low lead content in wetted components.

This valve is suited for water distribution, HVAC hydronic systems, and general plumbing applications where a reliable shutoff at 4-inch pipe diameter is required. The FPT end connections thread directly onto male pipe thread fittings or nipples, making it compatible with standard NPT piping assemblies. Its full port configuration is particularly valued in high-flow commercial systems where maintaining system flow capacity at the valve is critical to system performance.

Key Features

• Lead free construction meets potable water and code requirements for low lead content in wetted surfaces
• Full port design maintains pipe bore diameter for unrestricted flow and minimal pressure drop
• 4-inch FPT connections thread onto standard NPT male pipe thread fittings
• Substantial 15.73-pound build appropriate for commercial and industrial service
• Ball valve mechanism provides quick quarter-turn shutoff

Compatibility

Designed as an OEM-style replacement or new-installation ball valve for 4-inch NPT threaded plumbing and hydronic piping systems requiring lead free, full port shutoff service.

Installation Notes

Installation of a 4-inch threaded ball valve should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off and depressurize the water supply and drain the line before removing or installing any valve. Apply appropriate thread sealant or PTFE tape to male threads per manufacturer and code guidance. Support the piping adequately on both sides of the valve to prevent stress on the valve body after installation.
