Definition and useful information Have you ever wondered what material O-Rings are made of? Of course, the answers can be as different as the materials that give life to this important industrial component present in many products. Here are some of the terms frequently mentioned in case you want to…

In the immense and varied panorama of possible uses of an O-Ring, it is advisable to make a first macro distinction between the two types of basic applications (but fundamental as far as the design and sizing of the cavity and ring itself is concerned): static and dynamic applications. Let’s…

Although the O-Ring is not very suitable for dynamic applications (it is rather suitable for static applications), there are areas where it is used for seals on moving devices. Dynamic applications are defined as those where the seals act as dividers on the surfaces of two elements that move…

One of the applications in which the O-Ring is fundamental is that of drum presses. Drum presses are pumping and melting devices that allow the dosing of thermoplastic materials directly into the production line. They are usually made up of a piston (plate) press, a structure that guarantees rigidity to…

High and low temperatures greatly influence the behavior of elastomers High-Temperature effects on O-Rings At high temperatures, the compounds are subject to deterioration causing different effects: the hardness decreases, but the effect is reversed if the temperature drops again. the percentage elongation increases and, consequently, the load required to break…

The choice of an elastomeric material depends on many factors: temperature of use, environment, fluids/gases with which it comes into contact and for how long, mechanical, electrical characteristics, etc. O-Ring: The most important factors to consider when searching for the correct compound for each specific application. Chemical resistance Chemical resistance…
