METAL JACKETED GASKETS

Applications: Used for boilers and heat exchangers, suitable for narrow sealing faces.

Properties: Metal jacket provides increased gasket stability and blow-out resistance. Chemical resistance to a wide range of media can be accommodated by selection of a suitable metal.

Corrugated gaskets are a highly versatile family of products, available in wide variety of configurations and suited to a wide range of application. For improved sealing performances the gaskets can be partially or completely covered.

Types of construction:

• Double Jacketed: Constructed of soft filler encapsulated by a metal jacket and insert. High temperature & pressure application
  

• Single Jacketed: Constructed of soft filler covered by a metal jacket on both sides and one face. The gasket is ideal for narrow applications or moderate service conditions.
  

• Double Jacketed Corrugated (Soft Filler): The reduced contact area of the construction enhances compressive characteristics making it more suited to applications of lower bolt load or where flanges are uneven.
  

• Double Jacketed with Corrugated metal filler: A corrugated gasket encapsulated with a flat or corrugated jacket. Designed for applications where the available bolt load is limited but there is a requirement for the type of high integrity joint associated with an all-metal gasket.
  

• Single corrugated (No filler): Used mainly in valve applications and small recess gaps. The gasket is a wholly metal construction and therefore requires exacting conditions of flange surface finish and flatness.
