This collection groups lead-free brass check valves that the manufacturer identifies as meeting NSF/ANSI/CAN 372 for lead content. It includes swing and inline (spring) styles with threaded, copper-sweat, and IPS-threaded connections, from 3/4 in. to 4 in. NSF/ANSI/CAN 372 concerns lead content only; it is not a statement of potable-water certification, pressure or temperature rating, or any other performance or certification. Where a lead-content listing is required for a project, confirm the specific SKU's documentation.

Each valve in this collection is a lead-free brass body the manufacturer lists for NSF/ANSI/CAN 372 lead content. The group spans copper-sweat and female-NPT swing checks and IPS-threaded inline spring checks.
