LineBacker® 61™ NSF Certified Flange Isolation Gasket Kit
The LineBacker® 61™ sealing system uses a rectangular sealing element in combination with a unique groove design to effectively seal and isolate flanges for potable water and other low-pressure fluid piping applications. 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.
