Spiral Wound Gaskets
Spiral Wound Gaskets are made of a preformed metallic strip and a softer filler material, wound together under pressure, and
optionally with an outer guide ring. The metal strip holds the filler, resulting in excellent mechanical resistance, resilience and
recovery. The maximum working temperature is 450°C due to Graphite being used as the filler material.
