Most standard oil seals have to comply with the DIN 3760 and ISO 6194 standards. Different standard types of oil seals are available that comply with these requirements.
The most common and economical material within the sealing industry, Nitrile, is used in many oil applications, the automotive sector for aircraft fuel applications, military and marine applications, and more.
- In conclusion, the rear shock absorber oil seal, though seemingly insignificant, is a critical component that contributes significantly to a vehicle's ride quality and safety. Its role in maintaining optimal shock absorber performance and preventing contamination cannot be overstated. As such, regular inspection, prompt repair, and the use of high-quality seals are key aspects of responsible vehicle ownership and maintenance. Remember, investing in the health of your car's oil seals is an investment in its overall performance and your peace of mind on the road.
Grease - In the realm of engineering and manufacturing, a seemingly small yet critically important component is the rubber gasket seal. This humble element, with its intricate design and robust functionality, plays a pivotal role in ensuring the integrity and efficiency of various systems across diverse industries.
- The valve cover gasket's primary function is to prevent oil from seeping out of the engine and into areas where it could cause damage or compromise efficiency. A leaky valve cover gasket can lead to oil loss, which in turn can cause engine damage due to insufficient lubrication. Furthermore, oil dripping onto hot engine components can ignite, posing a fire hazard.
Multiple materials and compounds are used to make oil seals. Some of the oldest materials still used today include felt and leather compounds. However, the trend in mass production has experienced a shift towards synthetic elastomers or rubber.

An overview of the different standard types of oil seals and their main characteristics is shown below.
Minor lip The minor lip prevents the entry of dust and contaminants from outside.
Lubricant can be retained in the space between the main lip and the minor lip.
The hydrodynamic ribsa) have a two-stepped rib configuration provided in one direction on the air face of the lip. Even if the first rib is worn out, the second rib comes into contact with the shaft surface, meaning that this type of oil seal ensures higher sealing performance. Seal with Side Lip A large side lip ensures prevention of entry of dust/water.

Another factor you need to consider is the type of lubricants that are more suitable for the seals. Check for the appropriate viscosity of the lubricant that’s compatible with the seal material.
Industrial Oil Seals: Applications and Importance
Also known as a Rotary Shaft Seal, Shaft Seal, Lip Seal, Elastomeric Lip Seal or any variation of these. It is a simple device for excluding dust, dirt, water or any other contaminant whilst retaining lubricant in rotary shaft equipment. Generally, it has been developed as a means of protecting the bearings of rotating shafts.
