Check which chemicals your o-ring is resistant for, calculate your own cord length and cord thickness, get to know why your o-ring might be failing, and download material test reports at one of these pages.
O-ring materials react with various chemicals. You can compare this with chemistry. Because the materials react with each other, we take into account the reaction of the O-ring in the situation you specify per request. A good example is the following: There is a customer who is going to renovate his engine and needs O-rings. The EPDM material absorbs oil and is therefore not recommended for this case. By increasing our knowledge by learning the Chemical Resistence Guide, we can help you quickly with advice in any situation.
You can also find a failure analysis on our website. Here you can use pictures to find out what went wrong with your O-ring. So you can see which material, dimensions, Shore is best to use next time. If you have any questions about this, you can always email or call us, so we can guide you through the process.
