One of the widely used seals, the spiral wound gasket depends on the mechanical characteristics of a formed metal strip which works as a spring, offering a better resilience under fluctuated pressure & temperature.

How to choose Filler
The main sealing part is filler which is made up of SS strip and non- metallic filling tape,  the  material can be changed  according to different chemical compatibility requirements, 
Graphite filling strip is supposed to used in high temperature environment,  
PTFE filling  strip is for acids and other corrosive mediums 
Non – asbestos   its use increased when the health problems with asbestos became  known. Only  recommend  for low temperature less severe applications due to the rubber content . 
Ceramic is in extremely high temperature applications.The filler is not so common as it cannot achieve the same leak tightness as graphite
