How choosing the correct gasket reduces risks

Health and Safety across any industry are vital, especially so in industrial facilities and settings.  Why?  Because harmful leaks and emissions must be avoided at all costs to avoid serious accidents or injury to your teams and property.  That’s why having the right...

How to tighten your bolts perfectly

How to tighten your bolts and which tools you should use to achieve the perfect seal is not as seamless and straightforward as we would like. Various factors come into play in these situations, such as bolt grade, size, and even application type.  Tightening torques...

Static and Dynamic o rings

A range of factors and application dynamics come into play when choosing a particular type of o ring.  You need to understand the type of seal exert you require, the dimensions, and even compounds.  Due to the nature of an o ring and its overall design, o rings use...

Gasket Sealants

Fortunately, no one gasket suits a range of applications, but rather we have a multitude of gasket sealants available to meet various specifications and requirements.  Ultimately, sealants are used to effectively ensure gasket seals.  Helping to extend a gasket's life...

Types of industrial gasket material

Different industry sectors will use different types of gaskets and different types of gasket materials.   And of course!  Different industrial gasket materials will be much better suited to some industrial processes and applications compared to others.  As different...

Keeping a close eye on the gaskets your applications use

Gaskets are vital elements to any piping system and application that requires creating the perfect seal in order to prevent leaks.  This is the main role of a gasket, to provide a good seal, with some gasket materials sealing better than others in certain...

O Ring Colour Identification

O rings come in various colours, and it's important to understand what these colours indicate as the o rings you choose will affect your overall process application.  Ultimately, different o ring colours are used to help differentiate between different materials. ...

Spiral Wound Gasket Compressibility and Pressure Ratings

In order to form a reliable seal, spiral wound gaskets do require a certain degree of pressure.   The applied pressure allows the gasket to be compressed tightly between the mating surfaces preventing any leaks from occurring.  Factors such as operating temperature...

Elastomeric Compounds

What is elastomer?  Elastomeric compounds are rubber seals produced using natural rubbers or manufactured by the chemicals industry.  Elastomeric sealing compounds consist of between 50-60% rubber; the remainder of the compound consists of fillers,...

Is there such a thing as the right flange gasket?

We cannot stress enough how important gaskets and seals can be. Gaskets are vital for an application's reliability and integrity, and trust us when we say, choosing the right gasket now can help you avoid costly issues in the future.  Taking a closer look at pipe...

Kammprofile Gaskets for Your Industry 

Kammprofile Gaskets are grooved; covered metal gaskets consisting of a serrated metallic core with a soft facing material. The Kammprofile style gasket is mainly used in vessel applications where often the gasket width is limited. Kammprofiles are also often used as an upgrade on applications currently using metal jacketed gaskets due to the improved leak tightness, ease of installation and the possibility of reuse.

The depth and profile of the groove is specially designed to facilitate densification of the facing material and create a very leak tight seal even at relatively low bolt loads and with use on flanges with face imperfections.

Kammprofile Gaskets

Properties and Benefits of Kammprofile Gaskets 

  • Low Sealing Stress required for installation 
  • Suitable for a range of chemicals 
  • Suitable for use in high temperature and high pressure applications 
  • Can be manufactured to suit standard flange applications and vessels 
  • Can be manufactured for use with narrow flanges 
  • Can be used with uneven bolt loading situations 
  • Soft Facing material prevents damage to flange surface 
  • Can be refurbished and re-used 

Kammprofile Styles
Core Design Profiles 

The standard Core design is to have parallel grooves across the sealing face offering the advantages of even stress distribution.  

Alternatively, a convex profile is available reducing the depth of the groove towards the sealing face centre. This alternative style of design ensures a high sealing stress in the centre of the sealing surface making it more effective for low bolt load applications 

Expanded Graphite is the most commonly used facing material but others can also be used, PTFE for chemically aggressive duties and Mica for high temperature applications. 

Kammprofile Styles

Graphite 550C 
PTFE 260C 
Mica 1000C
