SPIRAL WOUND GASKETS
Designed more than 100 years ago, Spiral Wound Gaskets (SWG’s) are widely used as high integrity and sustainable gaskets. The sealing element is manufactured from preformed, V-shaped metallic windings with intermediate soft sealing fillers. The most common filler materials are Graphite and PTFE. Due to the gasket design, SWG’s offer high compressibility and recovery. Halo Sealing Systems SWG Style PM-ORIR is provided with an inner and outer guide ring. These gaskets are suitable for ASME B16.5 raised faced flanges up to 2500lbs and for EN/DIN flanges up to PN400.
