Beyond NBR and FPM

Other special materials in O-Rings

In the world of industrial sealing, it’s common to talk about materials such as NBR, FPM, EPDM, FFKM or VMQ. However, at JIOrings we know that market needs don’t always match the most popular compounds. That’s why we maintain an updated and diverse stock that includes a wide range of technical materials for O-Rings that are less well known but essential in specific and demanding applications.

Having these materials in stock allows us not only to offer fast delivery times but also solutions tailored to sectors as diverse as the chemical, energy or food industries, among others.

Below, we present some of the most technical and specialized O-Ring options available in our online store:
