Deltaone spiral wound gaskets are available in a variety of styles to suit the particular flange facing being utilized on the flanges. A winding is made of alternate plies of a metal wire and a soft non-metallic filler. The metal wire in the gasket is preformed into a "chevron" configuration, allowing superior resiliency and self-adjustment when compared to conventional gaskets. The Style W is just a sealing component (winding) only, which is normally used on tongue and groove joints, male and female facings and groove to flat flange facings.
