- Oil seals, often made from high-quality rubber compounds or synthetic materials, are designed to prevent the leakage of lubricants while inhibiting the ingress of contaminants. The 8 in the name likely refers to the percentage of oil-resistant material used in the seal's construction, enhancing its ability to withstand exposure to various oils and lubricants without degradation.
- In addition to regular maintenance, choosing the right type of spark plug for an aircraft engine is also important. Different engines have specific requirements for spark plugs, including the heat range, electrode gap, and overall design. Using the correct spark plug ensures proper ignition and combustion, leading to efficient engine operation and optimal performance.

In conclusion, auto parts oil seals, including the 99 Camry oil pump seal, are essential components in vehicle systems, contributing to the efficiency, performance, and reliability of automotive systems. Understanding the significance of these seals and their proper maintenance is crucial for optimizing the performance and longevity of the vehicle.
Before Installation
a)
The metal case is the exterior (or frame) of the oil seal, the principal function of which is to give rigidity and strength to the seal. The material of the case must be selected depending on the environment where the seals are to be used. Often the metal case is covered by the same rubber material used in the sealing element, which also helps seal the exterior of the oil seal in the housing bore. Common case material types are:
These types are made with a metal outer case and a PTFE lip. They are suitable for a wide range of temperatures from -90 °C to +260 °C.These lip seals can also be used for higher pressures of up to 10 bar (special types up to 25 bar) and rotational speeds of up to 40-45 m/s. Certain grades of PTFE are suitable for use in pharmaceutical and food applications. One important point is that PTFE lip seals do require a shaft with a harder, smoother finish.
Its sealing edge comes in full contact with the shaft surface in order to provide excellent sealing performance.
(See Figure 3.)
Sealing edge This refers to the component of the oil seal that makes contact with the shaft.
It is wedge-shaped to be pressed against the shaft surface and makes contact with the shaft to ensure sufficient sealing performance and suitability for operation at high peripheral speed.
Shaft Surface Finishing
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.
In our cutting edge technology centers in the Netherlands, the USA and the UK, we design and develop specific and custom-made rubber sealing parts for many industries.
Investing in quality seals will benefit you and your machine in the long run. The cost of replacing oil seals will be higher as cheaper alternatives are constantly being purchased. Not to mention, the efficiency and quality of low-cost oil seals may not be reliable.
