Components of engines, assemblies, and other products must be installed properly and tightly so they remain functional for the rest of their service life. One way to ensure the proper assembly of the components is through maximising mechanical seals.

Mechanical seals like gaskets can fill the space between two or more surfaces, preventing any leak from developing. Most of the time, sealing with gaskets are preferred by many industries since permanent sealing processes like gluing and welding may fail to provide a leak-tight sealing. Mechanical sealing is also maximised in most industrial applications since it can meet most of their assembly requirements.

To date, mechanical seals can be made from a wide variety of materials. But one material that is often used for mechanical seals is Viton.

Primary Composition of Viton

Viton is a mixture of synthetic rubber and fluoropolymer elastomers that comes from DuPont, a reputable producer of chemicals and science-based products. This material has been used in creating rubber seals, gaskets, and O-rings. To date, Viton has four families of polymers.

  1. A (Dipolymers of VF2/HFP) – This type of Viton polymer is comprised of 66% fluorine, making it effective for general-purpose sealing of automotive and aerospace products.
  2. B (Terpolymers of VF2/HFP/TFE) – Maximises 66% fluorine content, this type of Viton polymer is significantly useful for chemical process plants, power utility seals, and gaskets.
  3. F (Terpolymers of VF2/HFP/TFE) – F family of Viton is comprised of 70% fluorine. It can be effective in oxygenated automotive fuels and concentrated aqueous inorganic acids.
  4. Specialty Types – Specialty types such as GLT, GBLT, GFLT, and Viton Extreme can all be useful for the automotive and oil exploration industries.

Viton’s Remarkable Benefits

Since Viton comes from a reputable producer, it can easily provide benefits to industries that use sealing products out of this material.

One of the benefits of Viton sealing products is they can withstand extreme temperatures. From significantly hot temperatures down to extremely low temperatures, Viton sealing products can effectively resist these conditions and continue to seal various assemblies. Another benefit of Viton sealing products is they can resist oil and chemicals. Despite being exposed to these elements, Viton seals, gaskets, and O-rings can operate continuously and avoid unnecessary leaks.

Other elements that Viton sealing products can withstand include atmospheric oxidation, ultraviolet rays, climatic conditions, mould, and fungus.

Some more benefits of Viton are low burning characteristics and reputable electrical properties.

Maximising Viton Products

Viton’s remarkable benefits have paved the way for its usage across industries. Some industries that use Viton are aerospace, automotive, manufacturing, and transportation industries. As for their exact applications, Viton mechanical seals such as gaskets and O-rings have been very useful for retaining the service life and functions of pumps, valves, and engine components.

Tons of sealing products are now available in the market, ensuring that every application can be conducted successfully. One of the sealing products that industries use today is the gasket.

A gasket is a sealing product that can fill the space between two or more surfaces, ensuring that any leaks will be prevented on their connection points even when under compression. Without the installation of a gasket, the mating surfaces will easily allow external materials to enter and infiltrate them, which can damage them along the way. The lack of this sealing product can likewise lead to energy wastes, high expenses, and failure of the tools or components.

Many industries use gaskets due to their effective sealing capabilities. However, their applications differ from each other, which is why manufacturers have come up with various types of gaskets. Here are some of the industries that use gaskets and the best gasket types for their applications.

Food Processing

Temperature is a key factor when it comes to processing food products. And since a lot of food products are processed in various temperatures, the gaskets used for the tools and other equipment pieces should be able to sustain their qualities. One gasket type that can be effective in the food processing industry is silicone since it can remain stable despite being exposed to high temperatures. Gaskets out of graphite and non-asbestos can also be used in high-pressure environments. 


The number of cars that are being manufactured nowadays has been increasing exponentially thanks to the automation of manufacturing processes. However, to ensure that these vehicles can be effective and safe, they must maximise gaskets that can resist high temperatures, fuel, and oil. Gaskets with these qualities are often made from silicone, nitrile, and Viton. EPDM gaskets, on the other hand, are used in creating door seals and plastic foams for car seats. Graphite and non-asbestos gaskets, ultimately, are installed within the combustion areas of the engines as they can withstand high temperatures.

Oil and Gas

The oil and gas industry is another industry that maximises high temperatures in its applications. With the right gasket materials, the industry can easily process oil, gas, and other elements necessary to provide power. Gaskets made from graphite, for instance, can be effective in the oil and gas industry as they can work effectively in high temperature, high-pressure environments. The industry can likewise utilise gaskets made from non-asbestos materials.


The processes involved in the pharmaceutical industry can be delicate at times. And to prevent any accidents from happening, the industry should opt for materials that can handle chemicals and their respective reactions. They must also go for materials that do not allow bacteria to grow significantly. Fortunately, PTFE gaskets are effective in handling chemicals and preventing bacteria from growing. Silicone gaskets can also be maximised in this industry thanks to their durable composition.

Some more industries that use gaskets are aerospace, electrical, petrochemical, and transportation industries. To obtain quality gaskets for your applications, you can call us at Gasketech.
