Camprofile gaskets consist of a metal core, generally of stainless steel, with concentric grooves on either side. A sealing layer is usually applied on both sides and, depending on the purpose of this layer, can be graphite, PTFE (Teflon), Mica, or soft alloys such as aluminum or silver. The sealing material layers protect the flange surfaces from damage and provide optimum sealing.
Camprofiles have a wide seating stress range which makes them:
Camprofile cores are re-usable after cleaning, inspection, profile tracing, and relayering with new sealing material. This is of particular interest for costly heat exchanger gaskets when using exotic materials such as Monel.
