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...

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...

O-rings suitable for the pharmaceutical industry

O-rings suitable for the pharmaceutical industryO 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 use of a range of elastomers, polymers, and plastics (depending on the application of the o ring material).

At SSP, we find that o rings over the years have predominantly been used in aerospace and chemical applications. However, as advances in technology and applications continue at pace, we now see a range of requirements for o rings that are suitable for the pharmaceutical industry too.

Rubber o rings for the pharmaceutical industry 

Specially moulded and vulcanised to suit a set of strict requirements, o rings are now available in commercial and high chemically resistant materials. Providing users with a temperature range from -60 degrees Celsius to +327 degrees Celsius – making them highly suitable to meet a range of needs. 

The pharmaceutical sector, like others, requires sealing components such as gaskets and o rings for a wide range of laboratory equipment and analytical tools. 

These pieces of equipment are often subject to harsh chemical environments that are used for various testing procedures; hence they require extremely high and pure sealing capabilities. 

There is an incredible need to prevent contamination at all costs due to the inaccurate readings this could produce.   

Due to the nature of this industry, inaccurate results can negatively affect the outcome of a patient’s diagnosis, and even the right mix of chemicals to produce a new drug, for example. 

Pharmaceutical o rings 

Testing, researching, analysing, and even producing an extensive range of chemical, biological, and radiological products and substances mean this is also a sector that relies heavily on the utilisation of the right sealing product. 

Within the pharmaceutical industry, o rings, and specialist seals will be used in ventilators, CPAP machines, and even pharmaceutical manufacturing. 

Often o rings and other sealing products used within this industry will be cleaned by a prescribed process and using the correct materials. These products must also be dust-free, again to avoid contamination. 

It is also important that the rubber seals and gaskets used by the pharmaceutical industry are chemically resistant and can withstand fluctuating temperature ranges as required. 

Certain standards must be met, and compliance with prescribed regulations and guidance outlining what is suitable for specific sectors must be adhered to. 

O ring materials suitable for the pharmaceutical industry 

  • EPDM – can handle even the harshest of conditions; this synthetic rubber seal provides a high level of performance time and time again. 
  • Silicone or VMQ – extremely durable, this material is resistant to tears and can withstand wide fluctuations in the external environment. 
  • Fluorosilicone – offers a great seal from fluids and liquids and is mineral and oil resistant; however, the temperature ranges are a little more restricted compared to silicone o rings. 
  • Viton – offers a high tolerance to chemicals and fuels; this material also performs well under high temperatures (however, it is not suitable for steam applications). 
  • Nitrile – a very popular choice and suitable for applications using large volumes of liquids, oils, and fuels. 
  • FFKM – tough and robust, FFKM is also a thermoset elastomer and is available in different material grades to suit a range of applications and equipment.
