Modern engine oils, such as the current SG classification for gasoline engines, contain a large fraction of additives, many of which are detrimental to fluoroelastomers. The primary functions of oil-additive packages are to protect metal parts, avoid deposits in the engine, minimize oil degradation, and adjust fluid viscosity. Little attention has been paid to avoiding damage to rubber seals. Instead, elastomer producers have been expected to provide new, higher-performing products at no increased cost to auto manufacturers. Among the additives with moieties that may attack fluoroelastomers at high temperature are detergents (phenolates), dispersants (succinimides, alkylphenol amines), and antioxidants (amines, sulfides, hindered phenols).4 Many of these components are multifunctional, containing phenol or amine groups that can dehydrofluorinate and crosslink VDF-containing fluoroelastomers, leading to loss of elongation and eventual embrittlement. However, the rate and extent of reactions with seals are affected by many factors, including whether air is present in the system. When oil is exposed to air at high temperature, additives may undergo considerable changes. For example, a significant fraction of amines may be oxidized to amides, which have little effect on fluoroelastomers.5
- Replacing a failed cylinder head gasket is a job that should be performed by a qualified mechanic. Here are the general steps involved in replacing a cylinder head gasket
- In conclusion, the B20 series valve cover gasket is a small but significant component that plays a crucial role in the proper functioning of an engine. By preventing oil leaks and maintaining compression within the cylinder head, it helps to ensure optimal performance and longevity of the engine. As such, it is essential that drivers regularly check and replace their valve cover gaskets as needed to maintain their vehicles in top condition.
- A retainer oil seal is a crucial component in machinery that helps prevent oil leakage and ensures efficient operation. It is designed to seal the gap between two stationary parts, such as a shaft and housing, to contain the lubricant within the system.

- The spark plug, typically made from materials like nickel-alloy or iridium, is nestled within the engine's combustion chamber. Its primary function is to generate the spark that ignites the air-fuel mixture, initiating the combustion process. This spark, timed precisely by the ignition system, propels the piston, driving the chain around the guide bar, ready to cut through even the toughest wood.
3. Fluid types: Oil seals interact with oils, fuels, grease, water, and more. Choosing a seal material that is most compatible with your chosen medium can help to increase the durability of the seal and its internal components.
Have you found the right oil seal for your application? The next step is a precise and error-free assembly, so that the oil seal is fitted without being damaged. If you are replacing an existing oil seal, you must first disassemble it with the same care and precision. In this article, you will read all about the different steps of an appropriate (dis)assembly process that contributes to optimal operation within the application.
Oil seals are used to fill gaps between stationary and revolving parts of equipment, often known as radial shaft seals or rotary seals. These seals are frequently employed to keep impurities out and prevent lubricating oils, hydraulic fluids, or other liquids from escaping out of the system. An oil seal features:
What is Oil Seal
- Oil seals are typically made from materials such as rubber, silicone, or metal, depending on the specific requirements of the application. The seal is installed in a housing or bore around a rotating shaft to prevent the escape of oil or grease and to keep out contaminants such as dust and dirt.

Materials for Oil Seals
- The benefits of silicone gasket sheets extend beyond functionality. From an environmental standpoint, they offer significant advantages. Being highly durable, they require less frequent replacement than other types of gaskets, leading to reduced waste. Furthermore, silicone is a recyclable material, making it an eco-friendly choice for manufacturers and consumers alike.
Seal torque - 3. Chemical Processing Molded gaskets are ideal for use in chemical processing applications due to their resistance to chemicals and extreme temperatures.
- When it comes to maintaining the performance of your vehicle, one of the most important components to keep an eye on is the spark plug. The CMR5H spark plug is a popular choice among drivers due to its reliability and efficiency.
