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

The development of a custom seal requires a different approach from simply selecting an already available component. When geometry, material, operating conditions or installation requirements cannot be addressed by a standard solution, it is necessary to start from the real application and build a structured technical process. A custom-designed seal is not just a component manufactured with a customised shape. It is the result of a series of evaluations involving function, ma

FFKM is one of the highest-performing elastomeric materials for particularly critical sealing applications. It is considered when operating conditions exceed the limits of more common materials and when the seal must work in the presence of aggressive fluids, high temperatures or severe application environments. However, choosing FFKM does not automatically mean choosing “the best material” in absolute terms. A high-performance compound must always be evaluated in relation to
