H.S. White is pleased to now carry certified gaskets for potable water projects. When looking for drinking water components, especially drinking water system gaskets, there are three critical standard marks to look for:
- NSF/ANSI 61
- ASSE 1061
- ASTM F2854
These standards regulate chloramine resistance, tensile strength and purity of materials. All testing is rigorous and manufacturers are required to pass regular product tests and random annual inspections.
Specially formulated compressed gasket material based on NBR and aramid fiber, WaterSIL is a universal high-pressure gasket material that is certified to NSF 61 and meets strict chemical leaching requirements.
Applications: NSF/ANSI 61 certified gasket material for use in potable drinking water systems and fixtures for public drinking water, food and beverage, hospitality and plumbing supplies.
Benefits of Products Certified to NSP/ANSI 61 Drinking Water System Components
Potable water systems have miles of piping and other devices such as pumps, meters and valves. All of these components require gaskets. Gasket materials certified to NSF/ANSI 61 ensure the safe passing of water on its journey to the consumer’s tap.
NSF/ANSI 61 establishes minimum health effect requirements for the chemical contaminants and impurities that are directly imparted to drinking water systems. It also determines what contaminants may migrate or leach into drinking water and confirms that they are below the maximum levels allowed to be considered safe. Market leaders strive to attain NSF certification as a mark of distinction that assures their product does not leach harmful contaminants or impurities into drinking water.
Certification to NSF/ANSI 61 ensures that the product meets the Safe Drinking Water Act requirements that protect public drinking water supplies in the US. NSF/ANSI 61 certification can often meet or fulfill the testing requirements for many other countries as well.
THERMOSEAL WaterSIL is specifically formulated to meet the NSF/ANSI 61 standard for sealing materials. It also has excellent dielectric strength properties. The dielectric strength is the maximum working voltage a material can withstand without breaking down, thus limiting corrosion in pipeline systems.
Look for the THERMOSEAL WaterSIL logo and NSF mark on the packaging to ensure your gasket material complies with NSF/ANSI 61 – Drinking Water System Components – Health Effects.
