Gaskets and their use

Gaskets are a vital part of industrial life.

Used to fill the gap between two surfaces, helping to prevent leaks and vibrations, gaskets come in a variety of different types and materials.

In this post, we take a look at some of the most common gaskets and where they are primarily found/used.

Gasket Types by Material

Cork

Cork gaskets offer high compression and flexibility due to the cork being fully integrated with elastomer bindings.

You will find cork gaskets typically used in those sectors operating with fuel and oil, as well as other liquid solvents.

Non-Asbestos

Non-asbestos gaskets can be found in applications that incorporate oil, water, and stream.  Non-asbestos gaskets are made up of a combination of compressed fibres and elastomer bindings.

Rubber

Rubber gaskets are unique due to their high flexibility, meaning you will often find them across various sectors and applications.  Especially those that use heat exchanges and pipe gaskets.

Other Gasket Types

Transformer

Transformer gaskets are vital in preventing leaks in oil and water tanks.  Many industries also use transformer gaskets as weather seals to improve IP ratings and ensure those transformer areas remain accessible at all times.

Manways

Manway gaskets can be designed to suit a wide range of closed vessels.  Vessels such as fuel tanks and boilers primarily.  Hence you will often find manways ranging from oval shapes to ob.-round shapes and more.

Seals

Liquid seals

This is, of course, the essential premise of a gasket – preventing sealing fluid leakages.  These types of seals are well suited and found in sectors that involve fuel, oils, and again, any form of liquid solvents, due to their incredible resistance to liquid chemicals, such as Viton.

Anti-vibration

Anti-vibration seals are important in industries providing pipe support or structural bearings.

They offer additional support to other components and parts that are delicate and can be damaged due to any vibration or frequency.

Gaskets that support these components are they themselves supported with pads (gasket pads for the full term).

These gasket pads act as a barrier to the high frequencies and vibrations, creating the anti-vibration characteristics.

Environmental

Environmental seals play a big role in stopping impure particles coming into contact with finished products, helping to keep the integrity of components.

Gaskets in Piping

Full Faced

This type of gasket is designed to cover the whole flange.  Bolt holes are cut directly into the gasket material, making full-faced gaskets easily recognisable.

Segmented

Segmented gaskets are for those non-uniform shapes and nonstandard flanges. They are designed and created from various gasket elements, with the segmented gaskets’ shape then arranged to overlap.

The gasket categories we have listed above are three widely used categories; however, gaskets can also be broken down by the materials used within them, including metallic, semi-metallic, and non-metallic.
