- In conclusion, oil seal rubber parts are more than just a component; they are the silent guardians of mechanical integrity. Their role in preventing lubricant loss, maintaining system cleanliness, and ensuring operational efficiency cannot be overstated. As technology advances and machinery becomes more complex, the importance of high-quality, specialized oil seals will only continue to grow. Understanding and appreciating the role of these humble rubber parts is crucial for anyone working in or associated with industries that rely on precision machinery and efficient lubrication systems.


Fluid Types - Various oil seals are able to withstand interactions with oils, fuels, grease, water and more. Knowing what type of fluid the rotary shaft seal will be in constant contact with will ensure the longevity of the seal and surrounding components.


Oil seals are widely used as sealing devices for machines.
JTEKT's oil seals are described in our catalog, Oil Seals & O-Rings.
However, the catalog uses a large number of technical terms and is very long, so many people seem to have trouble handling it.
Therefore, this series of columns will summarize the following in order:
• The structure, functions, and types of oil seals
• How to select the right oil seal
• Handling of seals, and causes and countermeasures for oil seal failure
EPDM oil seals are less common. They are used in solvent, hot water and steam applications, EPDM resists low temperatures down to -50 °C and UV radiation well. Some types of EPDM are also suitable for higher temperatures up to +150 °C. EPDM oil seals are usually available upon request.
Some of the uses of o-rings are pipes, plates, flanges, and cylinders. They can also be found in cameras, and scuba gear.

In motor vehicles, spark plugs play a critical role in igniting the air-fuel mixture within the engine cylinders. High-quality iridium spark plugs are designed to provide reliable ignition, efficient combustion, and consistent performance, contributing to the overall efficiency and longevity of the vehicle. The use of iridium spark plugs in motor vehicles can lead to improved throttle response, smoother acceleration, and reduced emissions, enhancing the driving experience and environmental impact.
