Heat exchanger gasket is a term used for gaskets used in shell and tube type heat exchangers. This is usually a metal jacketed gasket with a soft filler for higher temperatures. The styles, materials, configurations are limitless.

 

Kammprofile gaskets are solid metal gasket which may have a soft outer sealing material in order to conform to flange imperfections. These gaskets are used in areas where extreme temperatures and excessive movement due to thermal expansion exist.
