- Oil seals serve as a barrier, preventing oil from escaping the confines of the machinery while also stopping contaminants from entering
Fit the gasket to the cover, making sure any screw holes line up. If the gasket has tongues, fit them into their cutouts.

Above, are all the components of an oil seal and all its naming conventions. Beyond selecting the correct size, the three primary selection criteria are Material, Lip, and Case. If you have an oil seal you’d like custom designed and made, send us your specifications through our Oil Seal Design Form.
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.

There are different types of spark plugs available, including copper, platinum, and iridium. Each type has its own advantages and disadvantages, so it is important to choose the right spark plug for your vehicle based on its specific needs.

Seals are classified by O.D. wall material, lip type, and whether they have a spring or not.
Major oil seals are specified in ISO 6194-1 and JIS B 2402-1.
Table 2 shows the common types of oil seals, while Table 3 shows the features of each type of oil seal.
Table 4 lists the JTEKT oil seal type codes and corresponding ISO and JIS standards.
The garter spring is located at the end of the primary sealing lip and used to apply pressure to the sealing lip against the shaft. Common garter spring material types are:


Rubber valve cover gaskets are crucial components in automotive engines, serving to create a secure seal between the valve cover and the cylinder head. These gaskets prevent oil leaks and contaminants from entering the engine, ensuring proper lubrication and protection of critical components. High-quality rubber valve cover gaskets are essential for maintaining the integrity and performance of the engine, contributing to optimal engine operation and reliability.
What are oil seals?
When selecting spark plugs for vehicles, it is essential to consider factors such as compatibility, heat range, electrode design, and material composition. High-quality spark plugs, including iridium spark plugs, are designed to withstand the demanding conditions of automotive operation, providing reliable ignition and combustion. Choosing reputable suppliers and manufacturers known for producing high-quality spark plugs is crucial to ensure the reliability and longevity of these critical components in the vehicle's ignition system.
There are a wide range of oil seals to select from for any number of uses, so this guide will break down the most common seals to help you choose the right one for whatever piece of machinery you are working on.
Application Industry
When deciding on the best type of seal for a particular application, it is best to consider all aspects of the environment and its purpose. If the application requires a spring- loaded seal, that does not eliminate either the rotary shaft seal or the mechanical seal. If the equipment is operating in extreme temperatures, including situations where the rapid movement of the equipment creates extreme heat, a mechanical seal will hold up better than an oil seal.
