Jacketed gaskets combine the temperature resistance of a metal jacket with the sealing performance of a soft filler. 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 following is a selection of the most commonly used styles. Call for help choosing the right style for your application.

	300 Single Jacket: The most basic form of jacketed gasket, with coverage on one face and both edges.
	301 Single Jacket with Overlap: Where full coverage is needed and flange is narrow relative to gasket ID.
	305 Double Jacket: Where full coverage is needed and flange is wide relative to gasket ID.
	306 Double Jacket with Double Shell: Stronger and more rigid than double jacket gasket.
	330 Double Gasket Corrugated: Corrugations create a labyrinth seal across the gasket face.
	340 French Style Jacket: Provides coverage on one side only (inside or outside) and both faces. Flange is narrow relative to gasket ID.
	345 French Style Jacket, two and three piece construction: For wide or irregular shapes. Available with coverage on either inside or outside edge and both surfaces.
	347 French Style Jacket, two and three piece construction: For wide or irregular shapes. Available with coverage on either inside or outside edge and both surfaces.

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
