Custom Bleed Ring with Flanged Flushing Connections
USA Industries NSF ANSI/CAN 61 certification applies exclusively to our stainless steel products.
NSF/ANSI 61 is the NSF standard ensures that any materials, coatings, or products that come into contact with drinking water do not leach harmful contaminants into the water at unsafe levels.
NSF 61 Covers:
- Pipes & fittings (metal, plastic, concrete, etc.)
- Valves & gaskets
- Meters & water treatment devices
- Coatings, linings, sealants, solders
- Any materials that touch drinking water in distribution systems
It Tests For:
- Leaching of lead, arsenic, mercury, and other heavy metals
- Leaching of organic contaminants (e.g., solvents, plasticizers)
- Other harmful chemicals that might migrate from the material into water
Why It Matters:
- It’s a regulatory requirement in most U.S. states and Canadian provinces for products used in public water systems.
- Products with NSF/ANSI 61 certification give assurance that they are safe for use with potable (drinking) water.
