Types of Flanges

Businesses in a variety of industries rely on flanges to join pipes or components together or to keep equipment secured to a surface. When it comes to choosing the best types of flange for your processes, you’ll want to take the time to research the different options...

Threaded Flange

Threaded flanges are probably the most recognisable of all flanges due to their screw thread design that is used to connect it to the pipe. Threaded flanges, also known as screwed flanges (for obvious reasons), require a male and female thread to create a connection...

Slip On Flange

A slip-on flange can also be known as a hubbed flange, which, as the name suggests, has a hub with a very low profile. Why is this important? Because this type of ring type joint gasket has an internal diameter larger than the connecting pipe, allowing you to slide it...

Weld Neck Flange

Also known as tapered hub flanges or high hub flanges, weld neck flanges are a specific type of gasket with a protruding ridge and long neck used to connect pipework and provide you with a high-quality seal. Weld neck flanges, in particular, are a popular choice when...

Nitrile vs Viton® – What is the Difference?

Aflas vs Viton

When it comes to choosing O ring suppliers in the UK, you’ll find that there are a wide range of materials on offer for you to choose from. Many people find that the options can seem quite overwhelming, with some materials having similar properties but offering...

EPDM Gasket

Both the automotive and construction industries have started to use EPDM gaskets more frequently in recent times. This rubber material is UV light resistant and has many fantastic properties that make this part highly effective for a wide range of processes. Keep...

Metal Gaskets

When comparing gaskets for use within your business processes, you’ll find that these can be made from a variety of materials. Metal gaskets are a very popular option, offering many advantages over other materials. When looking at sealing product options, make sure...

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.
