Viton O-rings are used in static and dynamic applications involving relative motion between parts.They are used in applications that have the possibility of friction. Viton O-rings exhibit chemical resistance and are the most suitable for use in pumps used for agricultural, disinfection, pest control, lawn care sprayers, and mold remediation. This is due to the resistance to hydrocarbons in some of the compounds. These applications are more suited to Viton O-rings because they can withstand sun exposure and other environmental conditions.

Types of Viton O-rings
The various types of viton O-rings include:
Type A Viton O-Rings
These types of Viton O-rings are made from di-polymers of VF2/HFP. They are general-purpose O-rings utilized in the automotive and aerospace industry. Type A Viton O-rings have a composition including 66% fluorine content.

Type B Viton O-Rings
These types of Viton O-rings are made from terpolymers of VF2/HFP/TFE. They are most suitable for use in chemical processing plants as well as power/utility applications. They have a composition that includes 68% fluorine content.

Type F Viton O-Rings
Type F Viton O-rings are highly resistant to concentrated aqueous inorganic acids, steam, water, and oxygenated automotive fuels. These types of Viton O-rings contain a fluorine content of 70%.
Specialized Type Viton O-Rings
These specialized O-rings are copolymers of TFE/propylene and ethylene/TFE/PMVE. They are the most suitable for application in the automotive industry and also for oil exploration, ultra-harsh environments, and sealing requirements.
Applications of Viton O-Rings
Viton O-rings are utilized in very harsh environments where chemical interactions and temperature extremes are common. They are utilized in appliance processing, chemical, and automotive industries. Their use is not only limited to those areas of application but goes further to transportation businesses, petroleum refining, aerospace companies, and oil and gas exploration industries.
Benefits of Viton O-Rings
The benefits of Viton O-rings in industries include:
- They are the most hard-wearing O-rings.
- They are high-performance O-rings due to the Viton material and are also very durable, making them the top choice for many different applications.
- Viton O-rings are incredibly versatile for difficult applications
- Viton O-rings exhibit high operating temperature ranges and better resistance to degradation when exposed to weather and ozone.
- They are more chemically resistant and are capable of withstanding a range of chemicals like oils, silicone fluids and gasses, acids, and aromatic and halogenated hydrocarbons.
- These O-rings are long-lasting, meaning they enjoy extended intervals between services. This, in turn, reduces the costs of maintenance and provides more reliable seals.
- Viton O-rings overcome most environmental challenges. They can maintain seals even in the presence of UV exposure, ozone, weather, fungus, oxidation, or mold.
Disadvantages of Viton O-Rings
The disadvantages of viton O-rings include:
Incompatibility
Viton O-rings are incompatible with ketones, including methyl ethyl ketone, acetone, ester solvents like ethyl acetate, organic acids like acetic acid, and amines.
Performance
Viton O-rings are not ideal for every application. For example, under excessively high temperatures, Fluoroelastomers can decompose and release hydrogen fluoride, which is toxic. It is also associated with ongoing irritation of the respiratory tract. At extremely low temperatures, Viton O-rings harden and become inflexible.
Choosing the Correct Viton™ O-Ring Supplier
To ensure you have the most productive outcome when purchasing Viton O-rings from a Viton O-ring supplier, it is important to compare several companies using our directory of Viton O-ring suppliers. Each Viton O-ring supplier has a business profile page highlighting their areas of experience and capabilities, along with a contact form to directly communicate with the supplier for more information or request a quote. Review each Viton O-ring business website using our patented website previewer to quickly learn what each business specializes in.
