Spiral wound gaskets

Spiral wound gaskets are used in challenging high pressure  environments. They have proven to offer exceptional safety up to temperature limits of for example 1000°C with ceramic fillers and, depending on matierals, pressure limits of up to 320 bars.

The spring-back properties compensate for the component expansion differences associated with pressure and temperature fluctuations and prevent the resulting sealing gap. This guarantees a reliable sealing function under harsh conditions.
