However, the correct design of the installation space also determines the performance of the sealing system.<\/p><p>As a <strong>general rule:<\/strong> Due to the lack of elasticity of the jacket, FEP-coated O-rings should only be deformed very carefully. Compared to elastomer O-rings, they can be stretched and compressed to a limited extent.<\/p><p>Designers can make it much easier to replace an FEP-coated O-ring if they provide axially accessible installation spaces. Split grooves are therefore preferable. If this is not possible, the fitter should always use an installation cone. This ensures even and controlled stretching.<\/p><p><strong>Professional tip:<\/strong> It helps to temper the O-ring in hot water for a few minutes before fitting.<\/p><p>All components involved must be burr-free. As with all sealing elements, the production of dirt-free surfaces is essential preparation for assembly.
