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
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
Offering:
- 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.
