O-Rings are among the most widely used sealing elements in industrial applications. Their simple geometry, availability in numerous sizes and compounds, and suitability for both static and dynamic applications make them appropriate for a wide range of systems. However, this apparent simplicity can lead to the selection phase being underestimated. An O-Ring with the correct diameter but made from a material that is incompatible with the fluid may deteriorate rapidly. Likewise,

Material selection is one of the most important aspects in the design and selection of a technical seal. Correct geometry and a properly dimensioned groove or housing may not be sufficient if the material is not compatible with the fluid, temperature, pressure or actual operating conditions. Elastomers, technopolymers and metals behave in very different ways. Elastomers are mainly valued for their elasticity and recovery capability; technopolymers offer chemical resistance, d

In gas systems, sealing solutions play a decisive role in ensuring operational stability, continuity of operation and long-term reliability. These are applications in which the seal cannot be considered a simple replacement component, but a technical element integrated into a complex system subject to pressure, thermal variations, operating cycles and specific application requirements. Choosing the correct solution depends on several factors: type of gas, operating pressure,
