1/2" Brass Ball Valve Threaded - Lead Free (942-LF-1)

The 1/2" Lead Free Brass Ball Valve (942-LF-1) is a compact, high-performance shut-off valve built for residential, commercial, and light industrial piping systems where reliable on/off control and lead-free compliance are required. Its lead-free brass body satisfies NSF 372 and Safe Drinking Water Act standards, making it the correct choice for potable water service and any application where local plumbing codes mandate lead-free components.

At 1/2", this is one of the most commonly specified valve sizes in the trade — appearing on fixture supplies, appliance connections, water heater inlets, irrigation laterals, and countless other branch line applications. Female NPT threaded connections on both ends keep installation fast and simple — just thread onto standard 1/2" NPT pipe or fittings with pipe tape or thread sealant. No solvents, press tools, or specialty equipment required.

The full port ball design keeps the flow path open to the full interior bore of the pipe, preventing the flow restriction and pressure drop associated with standard port valves — important even at the 1/2" size when serving fixtures or equipment with specific flow rate requirements. The chrome-plated brass ball turns against PTFE seats for a bubble-tight shut-off that stays leak-free and low-torque over years of service. The steel lever handle delivers quick quarter-turn actuation, with its position always serving as a clear visual indicator of valve status — parallel to the pipe is open, perpendicular is closed.

Rated at 600 WOG (Water, Oil, Gas), the 942-LF-1 handles the pressure demands of virtually any residential or commercial application with confidence.

• Commercial & Light Industrial Plumbing — Used on branch lines, equipment supplies, and utility connections throughout commercial buildings where 1/2" pipe is the terminal size
• Potable Water Systems — NSF 61 & 372 certified; safe for drinking water distribution in homes, apartments, schools, and healthcare facilities
• HVAC & Mechanical Systems — Common isolation valve on fan coil unit supplies, boiler make-up water lines, and small equipment connections in mechanical rooms
• Irrigation & Landscape — Reliable zone shut-off and lateral control for residential and light commercial irrigation systems
• Pool & Spa — Used on chemical feed lines, equipment bypass connections, and auxiliary water supply lines in equipment pad configurations
• Gas & Oil Service — 600 WOG rating covers natural gas and propane applications where brass ball valves are approved by local codes; always verify local gas code requirements before installation
