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...

Plastic gaskets, the best alternative to metal

Plastic gaskets and seals are not that uncommon.  In fact, they’re used in many devices due to the longevity and functionality they offer.  Helping to prevent leaks and maintain temperature control, plastic gaskets help equipment and appliances operate to the best of...

Protecting your seals

Dust gets everywhere.  We see it across the surfaces of our homes and even in our workplaces, especially when the light shines through to show it in its full glory!  However, dust that seeps and builds up within engineering equipment can be disastrous.  Causing damage...

Importance of durometer testing

Durometer or shore durometer is a way for industry professionals to measure how hard such things as plastic, rubber, and non-metallic materials genuinely are.  Its focus is to measure on a Shore A or Shore D scale, looking at how robust material is when examining its...

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.
