- The Art and Science of Skeleton Oil Sealing
When selecting car engine head gaskets and automotive rubber gaskets, it is crucial to prioritize quality, durability, and compatibility with specific vehicle models. High-quality gaskets are designed to withstand the demanding conditions of automotive operation, providing reliable sealing solutions that contribute to the overall performance and safety of the vehicle. Choosing reputable suppliers and manufacturers known for producing high-quality gaskets is essential to ensure the reliability and longevity of these critical components.
- Due to inboard springs that get adjusted as the seal faces wear, it is not required to do daily maintenance.
In engine applications, square rubber gaskets are used to seal various components such as valve covers, oil pans, and intake manifolds. These gaskets help prevent oil and fuel leaks, ensuring the engine operates smoothly and efficiently.

ERIKS type R (type A according to the DIN standard) is identical in shape to type M, but has a rubber outer case with metal reinforcement on the inside. The rubber creates a good seal in the housing, even if the housing has suffered minor damage or is not in its best condition for other reasons. The RST version has a dust lip. These types are often chosen to replace a type with a metal outer case because they are easier to install and can cope with minor damage to the groove, such as scratches.

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.

In addition to the installation procedure, our specialists and suppliers would also like to draw your attention to some cases that occur around oil seals.
Use an old screwdriver or scraper to carefully remove all traces of the old gasket from the cover and engine flanges.
