Properties of Spiral Wound Gaskets
Spiral wound gaskets comprise a solid metal ring to provide the strength and resilience of the gasket and a non-metallic component, generally Graphite, PTFE or Mica, to act as the sealing material. These are used in both high and low temperature and pressure applications.
Spiral wound gaskets combine the ease of sealing of a graphite, PTFE or mica filler with the strength afforded by a specially profiled metallic, spring-like reinforcement. The sealing element is manufactured by interleaving plies of alternating metallic winding strip and filler to create a gasket that is robust and easy to install.
Spiral wound gaskets can be manufactured from a wide range of metals to resist against chemical attack and temperature related degradation.
