NSF/ANSI Standard 61 establishes minimum health effects requirements for the chemical contaminants and impurities that may be indirectly imparted to drinking water. The LineBacker® 61™ Sealing/Isolating gasket is certified to conform with all criteria associated with NSF health effects testing, certification and production facility inspections.

Of particular importance with respect to NSF/ANSI Standard 61, is the micro-exposure of the sealing element (EPDM) within the G-10 Epoxy Glass retainer material. In addition to providing positive sealing characteristics relative to the fluid flowing in the pipe, the sealing element is also fully encapsulated between the flange and GRE retainer, reducing exposure of the sealing element to harsh outside atmospheric conditions.
