Metakamm® ActiVate

High recovery kammprofile type gasket with unique wave‑form core construction.

The Metakamm ActiVate gasket offers superior sealing performance for critical heat exchanger, piping and valve bonnet flange applications due to its unique grooved wave metal core that delivers outstanding compression and recovery characteristics. This core is supplemented by a choice of cover layers including high-purity graphite, PTFE and phlogopite.
