Why NSF/ANSI 61 Compliance Matters

In the drinking water industry, safety is non-negotiable. NSF/ANSI 61 is the American National Standard that establishes minimum health effects requirements for the chemical contaminants and impurities that are indirectly imparted to drinking water from products, components, and materials.

By utilizing Captain O-Ring’s certified materials, customers ensure:

  • Regulatory Peace of Mind: Full compliance with US and Canadian drinking water regulations.
  • Material Integrity: Assurance that sealing components will not leach harmful levels of contaminants from their devices.
  • System Longevity: Access to materials specifically tested and certified for extended performance in water treatment applications.
