- Over time, cylinder head gaskets can become worn or damaged, leading to leaks and reduced engine performance. Here are some signs that your cylinder head gasket may be failing
- In addition to oil leaks and low oil pressure, a failing oil gasket can also lead to engine misfires and poor performance. This is because oil plays a crucial role in lubricating the engine's moving parts and reducing friction. If the gasket is not sealing properly, the engine may not receive an adequate supply of oil, leading to increased friction and wear on the engine components.
Oil seals, which are also referred to as radial shaft seals, rotary shaft seals, grease seals, or fluid seals, are used to close the gaps between fixed and moving parts of mechanical equipment. They are put between moving and stationary mechanical parts to make sure that moisture, contaminants, corrosive materials, and abrasives don’t cause any damage to these parts.
These seals are designed to fit snugly around the shaft of the machine, preventing oil from leaking out while also keeping dirt, dust, and other contaminants from entering.
How are they used?

O.D. (outside diameter) surface The O.D. surface affixes the oil seal to the housing and prevents leakage , through the fitting area, of substances to be sealed, while excluding contaminants.
In conclusion, valve cover gaskets, head gaskets, and spark plugs are essential components in automotive engines, contributing to the efficiency, performance, and reliability of the engine. Understanding the significance of these components and their proper maintenance and replacement is crucial for optimizing the performance and longevity of the engine.

Oil seals made of HNBR are characterised by excellent properties that include high resistance to mineral oils with additives, low steam and gas permeability, good cold flexibility down to -30 °C depending on type, good ozone resistance and friction resistance. HNBR seals withstand heat up to 150°C.

The major cause of extrusion and nibbling is stress caused by high pressure. This is commonly noticed when the oil seal has a chipped or nibbled look. In fact, in some cases, the surface of the seal tends to peel on its own, which makes it have a shaved look. What the stress does is that it increases the clearance gap between the mating edges, which causes the seal to get entrapped, and then leads to severe physical damage.

This is one of the frequent reasons for oil seal failure, and this is majorly because of the volatility of any of the elastomer’s constituents. These causative constituents may be part of the elastomer formulation, or gases that got entrapped in the elastomer during the molding process. The deceiving fact about this failure is that sometimes the oil seal won’t show any visual sign of out-gassing, however, sometimes when the out-gassing is extreme, they shrink.


Rubber gaskets are essential components in many industrial applications, providing a reliable seal between two mating surfaces to prevent leaks or contamination. One common type of rubber gasket is the 40mm rubber gasket, which is used in a variety of industries for different applications.
