In the municipal water industry, compliance isn’t optional, it’s the law. As regulations around the Safe Drinking Water Act tighten across North America, water treatment facilities require components that guarantee safety. Flexaseal Engineered Seals and Systems provides peace of mind with mechanical seal assemblies that are fully certified to NSF/ANSI 61 standards, ensuring that no harmful contaminants leach into the potable water supply.
What is NSF/ANSI 61 and Why Does It Matter?
NSF/ANSI 61 is the legally recognized health effects standard in North America for all device components that come into contact with drinking water. From the intake pump to the distribution network, every part of the system must be vetted for safety.
While many manufacturers only offer “compliant materials” (certifying just an O-ring or a specific carbon grade), Flexaseal goes a step further. We provide certification for the entire mechanical seal assembly. This rigorous testing ensures that our seals meet the strict requirements for lead and chemical leaching, simplifying your compliance documentation and reducing liability.
