Viton Washers

Here at Advanced Seals & Gaskets, we produce 1000’s of washers from a variety of materials including special types such as Viton rubber, a high performance, durable synthetic material often used in applications requiring resistance to extreme temperatures and harsh chemicals. Viton rubber washers are produced on-site using drawings or measurements provided by our customers, with whom we work closely to ensure the final product is to their exact specification. 

Depending upon the size and quantity of washers required, one of many presses or CNC machines can be used to manufacture the final product, from one-off samples to multiple batch runs, we have a machine designed to quickly and accurately produce perfectly formed washers everytime.

Washers are a popular product as many industries require them for sealing against dust, air and moisture, gap-filling between uneven surfaces or for reducing unwanted noise and vibration. Viton rubber washers can be produced in different grades, each with different levels of resistance, formulated for use in different applications and environments.

What are Viton Washers?

Viton rubber is fluoroelastomer, a synthetic rubber that is fluorocarbon-based developed for high temperature and chemical resistance. Viton washers are a flat ring with an outer diameter (OD) and inner diameter (ID) measurement, cut from a sheet of material which is placed between two surfaces creating a level surface, acting as a spacer/ seal or between a nut/bolt to spread the pressure when tightened.  Due to its excellent resistance to many fuels, oils and acids and heat, Viton rubber gaskets are usually found used in the most demanding industries such as chemical processing and power generation.

    Washers can be used as a gap filler, dust/air/water seal, cushion or spacer.  We manufacture washers using an extensive range of other materials including neoprene, silicone, solid rubber, sponge, plastics, polyethylene, PVC, Polyester, cork, textiles and many more, using specialist presses and CNC machinery.

    Why use Viton Washers?

    There are many reasons to use Viton rubber washers, and it is often a go-to material for applications requiring a high-performance product to meet the demands that cannot be achieved using other polymers such as EPDM, Nitrile or Neoprene.

    Viton rubber washers can withstand extreme temperatures ranging from -20° to 275°C and can maintain their physical and mechanical properties without breaking down even when used with water, acids, petrol, chemicals and oil due to their excellent resistance.

    Viton rubber washers are a popular choice of material for use within the automotive, aerospace, oil and gas, and chemical industries - an FDA approved grade is also available for food and drink processing industries.

    Different Grades

    Advanced Seals & Gaskets work with a network of material suppliers and manufacturers, meaning we can offer Viton rubber washers in additional grades, the most popular of which are detailed below:

    Viton Rubber-Type B - has very similar properties and resistances to Type A, but has a greater fluorine content, which gives it better resistance to fluids and sulfur dioxide, better flexibility after heat exposure and a temperature range of -30°C up to +300°C. Type B is generally used in the most demanding applications and industries such as chemical and power generation. 

    Viton FDA grades are available in blue or white options.  This grade is suitable for use for food or pharmaceutical production even at high temperatures. FDA grade Viton rubber is extremely resistant to animal fats, oils, acids, chemicals and petroleum.

    Benefits of Viton Washers

    • Environmental resistance (Ozone, weathering, UV)
    • High Chemical Resistance
    • Weather Resistant  
    • Wide Temperature Range
    • Resistance to acid, oil and petroleum-based fluids
    • Withstand Challenging Environments

    Advantages of Using Viton Washers

    There are many advantages to using Viton rubber washers as the material is a high performance, versatile and durable, able to withstand high temperatures, is oil and chemical resistant  (even at high temperatures) and will not degrade as easily as other elastomers over time when in contact with chemicals and fluids such as oil, acids, ozone or UV.

    Other grades of Viton rubber are available to order for use in a range of specific industries, details of which can be made available upon request.  Viton rubber washers are available in a range of pre-manufactured thicknesses and the high resistance and durability of Viton rubber mean the washers are long-lasting and can be easily cut into the desired profile without the risk of tearing or stretching the material.
