DH-S-NPSEAL sealing gaskets use a rectangular sealing element enclosed into a unique groove to seal and isolate all types of flanges. This kind gasket can provide theoretical near zero “m” and “y” factors resulting in effecting a positive seal without excessive bolt loads required with flat gaskets. Materials such as Teflon and Viton also can be Used as the sealing element,which increases the choice of material.
NPseal sealing gaskets are widely used for low and medium pressure, but in order to get much better sealing performance, for the pressure equal to or higher than ANSI 600#, please consider HPSEAL sealing gaskets first.
