NSF 61 O-Rings

NSF 61-Certified O-Rings

The NSF (National Sanitation Foundation) ensures the safety of products involved in the treatment and distribution of water. NSF 61 (also referred to as NSF/ANSI Standard 61) restricts certain substances from breaching into drinking water at any point in the production process.

What does it mean to have an NSF 61-Certified o-ring? Specific rubber compounds have been tested by an independent laboratory and approved to be used in the process of water transmission and treatment. This means that o-rings listed as NSF 61 are not made with any of the NSF’s forbidden contaminants.
