Viton® O-Rings

logo-vitonViton® (fluorocarbon rubber, FFKM) has excellent resistance to high temperatures, ozone, oxygen mineral oil, synthetic hydraulic fluids, fuels, aromatics and many organic solvents and chemicals making it a good choice for an o-ring material.

Viton® is a synthetic rubber and fluoropolymer elastomer, which is commonly used in O-rings and molded or extruded products. There are four families of Viton® polymers, with a varying fluorine content between 66% and 70%. There are the main grades are A (Dipolymers of VF2/HFP); B (Terpolymers of VF2/HFP/TFE); F (Terpolymers of VF3/HFP/TFE); and specialty types (such as GLT, GBLT, GFLT & Viton® Extreme).

Low-temperature resistance is normally not favorable and for static applications is limited to approximately -15°F (-26°C) although in certain situations it is suitable down to -40°F(-40°C). Under dynamic conditions, the lowest service temperature is between 5°F and 0°F (-15°C and -18°C).

Gas permeability is very low and similar to that of butyl rubber. Special fluorocarbon compounds exhibit an improved resistance to acids, fuels, water, and steam.



  • Excellent Heat Resistance
  • Excellent resistance to oils and chemicals
  • Low compression set
  • Good fuel resistance
  • Excellent ozone and weather resistance (oxidation, sun, climat conditions, fungus, mold)


  • Engine oil seals
  • Fuel systems
  • High-Temperature Seals
  • Petrochemical Systems

Seal & Design is a leading supplier of Viton® O-rings and custom molded seals. We offer both genuine Viton® and standard fluorocarbon materials for general-purpose and high-performance applications. Selecting the type of Viton® that best fits your application is important, but it isn’t complicated, and help is available from Seal & Design. We also offer gaskets made out of Viton®.

Flange Analysis

Are you experiencing product problems due to unsatisfactory gasket performance or failure?
Do you have high maintenance or service costs due to leaks and blowouts?
Do you think you could seal with less expensive materials, but aren’t sure they will perform?

Introducing: Joint Imaging and Flange Analysis

The combination of advanced imaging technology and experienced sales engineers provides Seal & Design Inc. with the ability to analyze your problem and provide the solution. Below are a few examples of how we have used our advanced capabilities to solve customers’ problems:

  • Selected a material for an OEM pneumatic tool manufacturer that alleviated a chronic service problem. Tools were being returned weekly for gasket replacement. Seal & Design Inc. Analyzed the flange and recommended a sealing solution that stopped the blowouts.
  • Pinpointed several instances where applications were utilizing inappropriate materials. After testing and evaluating the data from alternate materials, Seal & Design Inc. was able to identify and provide the gaskets best suited to the applications’ requirements and stop the leaks.
  • designed custom engineered gaskets to overcome structural limitations of cast and machined flanges. Altering the gasket can require far less cost and save expensive down time.

How It Works

A thin, pressure sensitive tactile film is placed in your application along with the current gasket and torqued to the current specifications. This film is then removed and analyzed to provide a thorough report of the distribution of pressure levels throughout your application. Available analysis includes statistical reporting of pressure distribution, load variance, pressure histograms, and more. Seal & Design’s sales engineers will evaluate the results and suggest options, such as beaded gaskets, to correct your leaking problems.

Material Splitting


At Seal & Design, we have the unique capability to split master rolls of material into custom thickness at high tolerances. This makes us extremely competitive in weather stripping, insulation, and other sponge/foam applications. Material splitting is an excellent complement to our lamination and gasket fabrication capabilities.

Gasket Material

Selecting the right gasket material is an essential step in the planning of your application. You will need to anticipate the way the material will stand up to a given process, and be able to count on the manufacturing of such material to be efficient and affordable.

Whether your material metal, fiberglass, or rubber, you can count on Seal & Design’s material splitting services to split your rolls with accuracy. We have numerous gasket fabrication capabilities that will suit any of your complex application needs.

Waterjet Cutting


Waterjet cutting machines are a popular tool used to cut a wide variety of materials.

These machines use a very high-pressure jet of water, or a mixture of water and some abrasive substances, in order to cut through materials like granite, metal, rubber, and wood. Waterjet cutting machines suit numerous applications and can assist in the high production of materials that are too delicate for other cutting processes.

There are many more advantages of waterjet cut gaskets and parts:

  • Quick prototypes
  • Avoid tool costs, which can be significant for large parts
  • Intricate parts with thin walls can be easily accommodated
  • Multiple parts of the same material can be run at the same time, resulting in maximum material utilization, labor efficiencies, and reduced costs
  • Can cut materials up to 6″ thick
  • High-pressure water produces extremely perpendicular cut edges with virtually no concavity

Prototyping Tools

At Seal & Design, we offer our waterjet cutting machine capabilities as a prototyping tool, allowing you to create samples and production parts before fully investing in a product. Using industry standard *.dxf files, we can import customer supplied drawings directly into our nesting software and be ready for production within minutes.

TPS Trade Show – Houston, TX

tps-expo-logoSeal & Design will be exhibiting at the Turbomachinery & Pump Symposia in Houston Texas from December 12-14, 2017. (Rescheduled from September 12-14 due to the effects of Hurricane Harvey).
