U-Shaped Silicone Gasket: Applications and Advantages


Unthinkable in the list of seals are oil seals, which provide a seal against splashing oil. The most important oil seals are used for rotating shafts and valve stem seals. Oil seals are intentionally never completely sealed to lubricate the seals and prevent wear.
Significance of Quality Seals in Automotive Applications:
• Total eccentricity
• Rotational speed
• Substance to be sealed
• Lubrication conditions, etc.
A shaft’s surface finishing will determine how effective the sealing will be. The spiral lead and the direction of the finish tool marks have an impact on the sealing effectiveness. Therefore, it’s imperative to ensure that the shaft surface finishing is maintained.
Cover the valve gear with a clean cloth to prevent dirt getting into the working parts of the engine.
However, rubber-cased seals do have limitations. For example, during installation, shear stresses can build up between the seal and housing wall, causing the seal to release itself.
