This collection groups lead-free brass check valves that the manufacturer (Midland) designates as lead-free. It includes swing and inline (spring) styles with threaded, copper-sweat, and IPS-threaded connections, from 1/2 in. to 4 in. Lead-free here refers to the manufacturer's lead-content designation only. Apex has not independently verified an NSF/ANSI/CAN 372, NSF/ANSI 61, or potable-water certification for every model, and this listing is not a statement of potable-water certification, pressure or temperature rating, or any other performance or certification. Where a specific listing is required for a project, confirm the specific SKU's documentation.
