1-1/2" Brass Ball Valve Threaded - Lead Free (946-LF)

The 1-1/2" Lead Free Brass Ball Valve (946-LF) provides dependable quarter-turn shut-off for residential, commercial, and light industrial piping systems. Constructed with a lead-free brass body to satisfy NSF 372 and Safe Drinking Water Act compliance requirements, this valve is approved for potable water service and anywhere local plumbing codes mandate lead-free materials.

Female NPT threaded connections on both ends keep installation simple — no solvents, press tools, or specialty equipment needed. Thread onto standard 1-1/2" NPT pipe or fittings with pipe tape or thread sealant for a fast, secure connection. The full port ball design maintains an unobstructed flow path that matches the pipe's interior bore, keeping pressure drop to a minimum and preserving flow rates across the valve — particularly important on 1-1/2" branch and supply lines feeding multiple fixtures or equipment.

The chrome-plated brass ball turns against PTFE seats for bubble-tight shut-off with low operating torque, even after years in service. The steel lever handle delivers quick, positive on/off actuation, and its orientation always gives a clear visual read on valve status — parallel to the pipe is open, perpendicular is closed.

Rated at 600 WOG (Water, Oil, Gas), the 946-LF handles the pressure demands of most commercial and industrial service with a comfortable margin of safety.
