- High heat rubber gaskets are commonly used in industries such as automotive, aerospace, and manufacturing, where they are exposed to high temperatures and pressure on a regular basis. In automotive applications, these gaskets are used in engines, exhaust systems, and other areas where high temperatures are generated. They help to seal joints and connections, preventing exhaust gases and other fluids from leaking out and ensuring the proper functioning of the vehicle.
In this an auxiliary lip is provided along with the regular sealing lip. The additional dust lip protects the main sealing lip against dust and other fine solid contaminants and therefore this type is recommended for use in polluted environments. To achieve a long lifetime a suitable lubricant between the two sealing lips should be applied.
Failure Modes of Oil Seals
- Dynamic seals called bearing isolators are used to shield bearings from external impurities. They are revolving (rotor) and stationary (stator) elements. O-rings or strong seals are used in some bearing isolators, while they are constructed like labyrinths in others.

It is generally used in the union of two lubricated parts, so that it hermetically seals both sides. Therefore, it guarantees the proper engine operation and helps to maintain the vehicle’s distribution system in better condition.
Describe difference between mechanical seal and oil seal – Whether it is a mechanical seal or oil seal, it prevents the fluid seeping the liquid to other parts of the machine, or it keeps the rotating parts lubricated.
The car engine head gasket is a vital component that ensures the proper sealing of the combustion chamber, allowing for efficient fuel combustion and the containment of high-pressure gases. This gasket is subjected to extreme temperatures and pressures, making it essential to select high-quality, durable materials that can withstand these conditions. The car engine head gasket is crucial for maintaining the integrity and performance of the engine, contributing to the overall reliability and longevity of the vehicle.

Use the right assembly tools
As can be seen from the seal cross-section shown in Fig. 14.2, shaft seals are complex shapes that require advanced mold design and molding techniques (see Section 7.3 for discussion of fluoroelastomer molding). For some time, most shaft seals were made in the United States by compression molding. Injection molding of shaft seals is prevalent in Europe, and is being used increasingly in the United States. An advantage of compression molding is that preforms (usually rings cut from extruded tubing) are used that closely approximate the amount of stock required for the final parts, so compound waste is minimized. For injection molding, the amount of cured stock in the central sprue and runner (actually a thin sheet leading to the seal lip) is often large compared to the stock required for the final part, so the waste of high-cost fluoroelastomer may be high. Such waste is reduced in modern injection molding designs.
