- Rubber tube gaskets come in a variety of shapes and sizes to accommodate different fittings and connections. They can be easily customized to fit specific requirements, ensuring a precise and secure seal. With their flexibility and versatility, rubber tube gaskets are ideal for use in a wide range of applications, from household plumbing to heavy-duty industrial settings.
- Another important feature of radial oil seals is their ability to withstand high pressures and temperatures

ff 10 spark plug. Whether you drive a compact car, a heavy-duty truck, or a high-performance sports car, you can trust that this spark plug will deliver the performance and reliability you need.
Requirements of the shaft
Even more important than a correct interference fit of the Oil Seal is a perfectly smooth shaft in the region of the seal, particularly if shaft surface speed is high and the medium to be sealed is under a certain amount of excess pressure. The surface roughness of the shaft depends on the average profile depth Ra of the tool marks caused by the machining process. Oil Seals made of PTFE require, independent of the surface speed, a surface roughness of between 0,1 to 0,2 mm, because PTFE has less wear resistance than rubber seals. For normal circumstances, the shaft in the region of the seal must have a surface roughness of approximately: To summarize, the surface of the shaft in the region of the seal should not have noticeable machining marks. For pivoting shafts and other difficult or critical sealing applications, it is recommended that Oil Seals with a helical groove hydrodynamic pattern, which has a pumping effect, be used. When grinding and polishing, an axial movement of the grindstone along the shaft must be avoided in order to prevent machine lay.
Sealing of lip type seal is normally a result of an interference fit between the flexible sealing element, usually augmented by spring pressure and a shaft. Fluid retention is based on the precise amount of lip contact pressure. In most lip seals, increased fluid pressure in the sealed area causes lip contact pressure on the shaft to increase.
