NSF/ANSI 61 gaskets are specifically engineered and certified for use in potable water systems, ensuring they do not leach harmful contaminants or affect water quality. These gaskets are tested to meet rigorous safety and health standards set by the National Sanitation Foundation (NSF) and are approved for contact with drinking water. Ideal for municipal water treatment, water distribution systems, and plumbing applications, NSF 61-certified gaskets are available in a variety of materials, including compressed non-asbestos, PTFE, and EPDM. They provide safe, leak-free sealing in flanged joints, pumps, and valves handling drinking water or other sanitary fluids.
