Metal Jacketed & Corrugated Gasket

Metal Jacketed Gasket

Metal Jacketed gaskets are the most basic type of semi-metallic gaskets combining the high pressure suitability and blow out resistance of metallic materials with the improved compressibility of soft materials. Metal jacketed gaskets offer an economical seal where sealing faces are narrow and can be produced in a variety of shapes, making them a good option for heat exchanger jointing.

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

General Properties 

Economical 

Easy to handle and install 

Suitable for high temperatures 

Suitable for narrow flanges 

Good blow-out resistance

Applications 

Heat exchangers 

Exhaust gases Valve 

bonnet gaskets 

Narrow flanges 

Metal Jacketed and corrugated gaskets can be manufactured to suit a range of chemical environments by the selection of a suitable alloy jacket or core. The following materials are available:

Types of Metal Jacketed Gaskets

Double Jacketed Gasket 

Constructed of soft filler 

encapsulated by a metal jacket 

and insert. Designed for use on

high temperature and press ure

applications 

Single Jacketed Gasket 

Constructed of soft filler 

covered by a metal jacket

on both sides and one face. 

The gasket is ideal for nar-row 

applications or moder-ate

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.

Single Jacketed Gasket Open on Outer Diameter

Ideal for narrow applica-tions where protection of the soft filler on the inner diameter is a requirement. Used in valve bonnets, sight glasses and vaccum seals.

Single Corrugated (No Filler)

Used mainly in valve applications and small recess gaps. The gasket is a wholly metal construction and therefore requires ex-acting condtions of flange surface finish and flatness

Single Jacketed Gaskets Totally Enclosed 

Constructed of soft filler completely enclosed in a single jacket for use in ap-plications where the width does not permit the use of a double jacketed gasket.

Corrugated with Cord Rope Facing Corrugated metal

core with a non-abestos rope facing. 

Designed for poor or pitted flanges or where the available bolt load is low.

Double Jacketed with Corrugated Metal Filler

A corrugated gasket encap-sulated with a flat or cor-rugated jacket. Designed for applications where the available bolt load is lim-ited but there is a require-ment for the type of high integrity joint associated with an all-metal gasket.

Corrugated with Soft Facing Layer

Comprises a single corru-gated core faced with either PTFE or Graphite depedant on application. The soft facing layer provides the gasket with a high level of tightness while the core gives the gasket both resil-ience and integrity. Used in variety of applications including heat exchangers, valve bonnet applications and small recess gaps.

Double Jacketed 

Applications: 

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

Typical 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
