The toric seal or O-ring gives your machines the tightness they need. As it is available in many different diameters, strengths and materials, the toric seal is one of the most common and versatile spare parts. Together with the valve stem seal, for example, it is responsible for ensuring that an injection valve is tight. The service life is heavily dependent on factors such as mechanical stress, the place of use, but also maintenance. Toric sealings that have become porous should be replaced as a matter of urgency, otherwise a leak can occur, which in the worst case can have serious consequences for your engine.
