Corrugated metal gaskets can be direct replacements for spiral wound gaskets. It can eliminate inward buckling issues while creating a seal at moderate flange stresses.

Corrugated metal is covered with graphite, ceramic, or PTFE layer. An additional finishing layer is applied depending on the requirements of the medium to be sealed. The gaskets with a soft layer on both sides are used in low-pressure applications in large diameter flue gas ducts at high temperatures
