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.

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.
