Flange Faces

As you start to consider purchasing flanges or gaskets, you’ll see a variety of terms used that you may not have come across before. Flange faces are the surface area that will receive the gasket, allowing them to come together to create a seal when put under...

Octagonal Ring Type Joints

A ring-type joint is a metallic ring that is machined to sit between two mating surfaces, where it will be compressed to provide a high-quality and reliable seal. Ring-type joints are vital components in various applications across multiple industry sectors,...

Blind Flange vs Blank Flange

Small pieces of mechanical equipment flanges continually play a vital role across numerous industries and applications. In essence, we use flanges to connect pipes to each other, with flanges also found in valves and specific application fittings too. Due to the...

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?

As you start to make a decision about what type of O-rings to purchase for your business, you might wonder what material is the most suitable for your unique needs. Every business operation has different requirements for their O-rings, such as the temperature,...

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...

Viton O Rings

Viton o rings bring with them numerous advantages, especially for applications within high-tech and critical industries.

Providing great resistance to wide fluctuations in temperature and chemical ranges as well as being wholly suitable for pressure applications, Viton o rings can provide advanced sealing capabilities when we compare them to their silicone counterparts (check out our latest post on the advantages of silicone o rings and the applications/industries where this type of sealing gasket is most suited).

At SSP, we provide a wide variety of seals and gaskets; however, if you’re looking for a more reliable seal for a particular critical application, Viton o rings could be the perfect solution.

Viton O Rings Complete Guide

Viton O Rings

Viton is part of the fluoroelastomer (FKM) family, meaning it has strong carbon-fluorine bonds, making it super versatile and resistant to chemicals, extreme heat, and oxidation.

The synthetic rubbers based on fluoroelastomers allow Viton o rings to keep their shape even after repeated compressions.

Due to their chemical makeup, Viton o rings are renowned for being highly dependable and suitable for the automotive industry, chemical, oil and gas, aerospace, and heavy-duty sectors used within applications such as:

  • Aircraft engine seals
  • Fluid system seals
  • Chemical processing equipment
  • Tubing and hosting
  • Sterile processing applications in the pharmaceutical sector
  • Drilling and production equipment


  • Chemical resistance
  • High density
  • High quality
  • High performance under a wide temperature range
  • Weather and ozone-resistance
  • Gas and liquid-resistance
  • Good mechanical performance
  • Resistance to burning.

We’ll take a look at some of these benefits in more detail below.

Benefits of Viton o rings UK

Can withstand wide temperature ranges

Due to the makeup of Viton o rings, they can withstand extreme temperature ranges while also maintaining flexibility, keeping their shape, and maintaining all mechanical properties.

Suitable for temperatures ranging from -13 degrees Fahrenheit to 446 degrees Fahrenheit make Viton o rings the perfect and trusted choice for various medical devices.

Due to its resistance at high temperatures, the o ring can also resist degradation (a process that occurs after long exposure to high-temperature environments), remaining robust and sturdy in long-term applications.

Provides chemical resistance

Viton o rings provide an excellent seal against even the harshest chemicals that destroy most rubber materials.

Resistance to chemicals and other gases means that you can rely on this type of seal to remain durable and provide a high level of sealing quality – ideal for critical sealing environments.

Protecting against oils, acids, silicone fluids, oxygen, glucose, and carbon dioxide, Viton O-rings are often the sealing solution of choice for the automotive and aerospace industry.

Remain strong under pressure

Where rubber material-based o rings would become brittle under pressure, Viton o rings are resistant to compression.

Offering high tensile strength, Viton o rings can withstand stretching without breaking, making them also tear-resistant – ideal for applications with sharp edges or rough surfaces.

Abrasion resistant

The reason why many o-ring suppliers opt for Viton o-rings is due to their resistance to friction, making them able to withstand wear and tear, hence having a long lifespan.

This makes them an incredibly reliable and durable option for many applications, reducing the likelihood of failure and the need for frequent replacement, which in turn reduces your overall costs.

Choosing the right seal for your application

It’s essential that you choose the o ring material that is most suited to your application. For example, if you’re looking for a low-friction, nonstick material with a good level of chemical resistance, PTFE could be the best material choice.

Alternatively, silicone is more versatile for wider operating temperature ranges and those requiring electrical resistance properties (an o-ring of choice for the food and drug industry).

EPDM is most suitable for outdoor use where the application is exposed to weathering or low temperatures. And Nitrile is one of the more cost-effective solutions, suitable for tanks, hoses, automotive seals, etc.

Viton o rings also come in various grades, and it’s important to be aware of this and choose the grade and material makeup that is best suited to the application. Maintaining its shape and flexibility even at high temperatures, Viton is the o ring of choice when focusing on long-term applications to avoid downtime and reduce maintenance costs.

Viton is also bio-friendly and meets strict FDA guidelines, making it suitable for a wide range of industries.
