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...

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...

The Evolution of Gasket Solutions

gasket evolutionWhen we talk about gaskets and the history of a gasket, we must start at the very beginning. 

What is a gasket? 

Ultimately, a gasket is a manufactured seal that is used to fill the gap/space between two or more surfaces. 

Gaskets are typically manufactured by cutting sheet materials, offering complete flexibility in their ability to fit any application or process. 

Most gaskets will undergo a series of compression tests to understand its ability to withstand compressive loads and fluctuating temperatures. 

Gasket History 

Helping to fill the void between mating surfaces since the early 1800s, seals found dating back to 1820 were manufactured using a combination of iron filings, water, and sulphur powder. 

Before this, however, gaskets were made from pieces of rope called Oakum. 

Ultimately, Oakum was the loose fibres found and obtained by untwisting old rope. During these times, the rope would be pulled apart, tarred, hammered, and caulked. 

Primarily these seals were designed for use in the seams of boat hulls or within the edges of steam pistons, where they would be held in place by weights (this is not too dissimilar to modern-day graphite valve packing). 

Leather gaskets could also be found at this time within water pumps, although leather was not a great material when it came into contact with heat and often ripped apart when it came into contact with steam. 

It wasn’t until the 1850’s that rubber gaskets were invented. And by 1923, the first significant gasket supplier was founded in the UK. Whitby Chandler Ltd. 

Whitby Chandler Ltd was instrumental in the development of sealing technology and, in the 1960s, soon began manufacturing compression rubber mouldings to work alongside gaskets. 

Leading the way in this development, Whitby Chandler Ltd developed new high-tech machinery for gasket cutting as well as replacement products from asbestos. 

By 1899 Richard Klinger became known for developing the first asbestos fibre gasket. With sheet gasket packing in this sense being used to seal and insulate locomotives and engine boilers, supporting engine parts and mechanical operations. 

By the 20th Century, asbestos was the most popular material to be used and the material of choice for most gasket manufacturers. 

These asbestos-related gaskets offered, at the time, an ideal solution, as they could withstand steam, chemicals, water, and high pressure. Typical applications they were used in, included the transportation of hot oils, gases, acids, and grease in mechanical systems, pumps, compressors, turbines cylinder heads and more! 

By the 1980s, however, the use of asbestos began to decrease, with more and more companies now using alternative fillers for their gasket materials. 

Note: The use of asbestos is now prohibited in the UK and Europe due to the severe health risk the material poses. 

Today gasket manufacturers use materials such as rubber, metal, paper, silicone, neoprene, cork, fibreglass, plastic, polymers, and nitrile rubber. They can be used across a wide variety of applications covering a whole host of industrial sectors.
