The Spiral Wound “SWG” Style CG consists of a centering ring with a windings (sealing element), typically a Carbon Steel outer ring with 316SSL Windings and a Graphite Filler.
An integral centering ring (Outer or Guide ring) assures fast, accurate centering of the gasket on the flange. It also acts as a compression limiter to prevent over compression of the winding (or sealing face) of the gasket.
