Fladetætningsringe

Fladetætningsringe, commonly known as flat face seals or O-rings for flat surfaces, are essential components in mechanical systems designed to prevent leakage between two mating surfaces. These seals are typically made from elastomeric materials such as rubber, silicone, or neoprene, although they can also be manufactured from metals or plastics for specific applications. The primary function of a fladetætningsring is to create a barrier that contains fluids or gases under pressure.

The design of a fladetætningsring is straightforward. It is a circular ring with a generally rectangular or square cross-section, intended to be compressed between two flat, parallel surfaces. When the two components are assembled and fastened together, the fladetætningsring is squeezed, causing it to deform and fill any microscopic imperfections on the sealing surfaces. This deformation creates a positive seal, effectively blocking the passage of the contained medium.

Fladetætningsringe are widely used across various industries, including automotive, aerospace, hydraulics, pneumatics, and general engineering. They are commonly found in applications such as pipe flanges, valve bonnets, pump housings, and engine components. The effectiveness of a fladetætningsring depends on factors such as the material selection, the groove design in which it is seated, the compression applied, and the operating temperature and pressure of the system. Proper installation is crucial to ensure a reliable and long-lasting seal.
