Jacketed gaskets combine the temperature resistance of a metal jacket with the sealing performance of a soft fille. The jacket and filler materials are selected to optimizes temperature and chemical performance; construction style is dictated by pressure needs, gasket geometry and sealing issues.
Styles
There are many different styles of jacketed gaskets available. The follow is a selection of the most commonly used styles. Call for help choosing the right style for your application.
I Double Jacket with Double Shell: Stronger and more rigid than double jacket gasket.
II Double Jacket: Where full coverage is needed and flange is wide relative to gasket ID.
III Single Jacket with Overlap: Where full coverage is needed and flange is narrow relative to gasket ID.
Fillers
A metal jacket extends the temperature and pressure range of the filler.
There are five main types of filler:
Non-asbestos
Flexible graphite
Ceramic
PTFE
Corrugated metal
