O-rings suitable for the pharmaceutical industry

O rings are widely used across various industries to support a variety of different pieces of equipment and applications.  They provide an essential function and are ultimately moulded and manufactured to ensure they provide a continually high level of quality through...

The Best Chemical Resistant Gaskets for Sulfuric Acid

If you are using sulfuric acid on a regular basis within your industry, you might be aware of how corrosive it can be. While it can be useful for dyes, explosives, fertilisers, and many more applications, finding a chemical resistant gasket can often be one of the...

Different elastomers for o rings and various applications

An elastomer is a primary raw material used for most o rings. They are typically manufactured as gum rubber or manufactured synthetically, and surprisingly today, there are approximately over 32 different synthetic rubbers now available.  Elastomer compounds will...

Spiral wound gasket thickness – what’s best?

It is often recommended that using a thinner gasket type/material will result in better sealing performance.  Why?  Because thinner gaskets tend to require much less gasket stress to provide applications with the perfect seal, they also have an excellent response to...

Choosing the correct oil seal application

Choosing and using the proper sealing devices within oil and gas applications can be vital when preventing dirt, dust, water, and other debris from potentially getting inside and contaminating products.  Of course, all rubber materials and seals will provide a range...

Nitrile rubber, NBR, and Buna-N – how well do you know your o ring materials?

A widely used elastomer, Nitrile, Buna-N, or NBR rubber, are all oil and fuel resistant and provide a great level of strength, making them a popular material for seals across various industries.  Suitable for a range of applications, this versatile rubber material,...

Optimum squeezing force for an o ring

It is true that the more squeeze you place on an o ring, the tighter the seal it will provide. In essence, the more squeeze (compression) you apply, the greater the force between the o ring and its mating hardware.  And ensuring you have the perfect seal is all...

O Ring Squeeze

The squeeze and shrinkage on an o ring are vital to understanding as these factors stand in the way of your application either experiencing a perfect seal or your application suffering from leaks.  You can measure the shrinkage of an o ring during...

Keeping your o rings bonded

EMI o rings. Those seal ring gaskets are made of silicone compounds, combining environmental sealing with electromagnetic interference protection.  Consisting of metal or metal-coated particles, silicone o rings are filled with silver, silver aluminium, or nickel...

The importance of mechanical seals when reducing water consumption in mining

Environmental considerations are at the top of most industry's agendas in the 21st century as companies evaluate and improve operations, processes, and systems.  Conserving water in mining is one such area that is now being investigated further with the rotation of...

Types of Gaskets and its Usage

Gasket TypesGaskets are essential industrial components used to fill the gap between two surfaces to prevent vibration and avoid leaks. There is a wide range of gasket types available in the market and each one of them is differentiated according to its usage, characteristics and material. Go through the following details to know how gaskets are classified:

Gaskets classified by material

Cork Gaskets:

When the cork is integrated with elastomer bindings, it produced a product with high compression and flexibility. These gaskets are mostly used in the industries that deal with fuel, oil and other liquid solvents.

Non-Asbestos gaskets:

These kinds of gaskets are manufactured by combining elastomer bindings with compressed fibre. They are used in a wide range of applications like oil, stream and water.

Rubber gaskets:

It is a unique form of a gasket that is mostly used for heat exchanges and pipe gaskets. On virtue of its high flexibility, this gasket is used in a wide range of industries.

Other forms of gaskets

Transformer gaskets:

These forms of gaskets are used to prevent leakage in water and oil tanks. They can be used as weather seals to enhance the IP rating of sections thereby making sure that the transformer area remains easily accessible.

Manway gaskets:

These kinds of gaskets are mainly used in closed vessels such as boilers and fuel tanks. Manway gasket types are subject to a wide range of design requirements ranging from an oval shape to an ob-round shape.
Gaskets divided as per their usage

Liquid seals:

Sealing fluid leakage is one of the most important functions of gaskets. Most of the typical forms of gaskets offer amazing resistance to liquid chemicals like Viton. These kinds of gaskets are best suited in the industries that involve dealing with fuels, oils and any other form of liquid solvents.

Anti-vibration:

Anti-vibration techniques are mostly used in industries that deal with structural bearings and pipe supports. The process emits a lot of frequency and vibrations that may damage the other components which are quite delicate. Gasket pads that come with anti-vibration characteristics disrupt these high frequencies and vibrations.

Environmental seals:

In most industries, it becomes essential to keep the integrity of components by allowing them to get in touch with any forms of dirt or dust particles. This is where environmental seals have a vital role to play as they don’t allow any kind of impure particles to get in contact with the finished product.

Gaskets used in piping

Full faced gaskets:

Full faced gaskets are something that covers the entire flanged. They are very easy to recognise mainly because the bolt holes are cut into the gasket material directly.

Segmented gaskets:

These are mainly used whenever the flange is in a non-uniform shape. Segmented gaskets are manufactured from multiple gasket parts which are being arranged in overlap shapes.

Apart from the several categories mentioned above, gaskets are also classified according to the materials used in them. It mainly consists of metallic, non-metallic and semi-metallic. The more you try to explore the subject of gasket types and their usage, the more you will end up discovering.
