- The white color of these gaskets is often preferred in certain industries as it provides a clean and professional appearance. In addition, white rubber is typically made from materials that have good resistance to heat, chemicals, and weathering, making it suitable for use in demanding environments.
Figure 5 explains the JTEKT seal numbering system.
Seal numbers consist of
(1) the seal type code,
(2) the spring code,
(3) the lip type code,
(4) the dimensional numbers, and
(5) the special type code,
and Table 6 shows examples of each of these codes/numbers.- Radial lip seals are the most common type of oil seal used to prevent leakage of fluids such as oil or grease in rotating machinery. They consist of a metal outer casing with an elastomeric sealing lip that is pressed against the shaft to create a tight seal.
- A head gasket, as its name suggests, is a crucial component that seals the interface between the engine block and cylinder head. It maintains the pressure within the combustion chambers and prevents the mixing of coolant and engine oil. When a car overheats, the intense heat can cause the head gasket to fail, a situation known as a blown head gasket.
- Another important feature of 7mm spark plug wires is their ability to reduce electromagnetic interference. As the high voltage current travels through the wires, it can create electromagnetic fields that can interfere with other electronic components in the vehicle, such as the radio or navigation system. 7mm spark plug wires are designed to minimize this interference, ensuring that all systems in the vehicle operate smoothly and without any disruptions.
- Changing a valve cover gasket is a routine maintenance task for car owners or mechanics, particularly when dealing with engine leaks or performance issues. The valve cover gasket, a crucial component in an internal combustion engine, seals the gap between the cylinder head and the valve cover, preventing oil from spilling out and contaminants from getting in.
With minor lip type Used for applications where there are contaminants, such as dust and foreign matter, on the air side face of the oil seal.
2. How to select the right oil seal

However, it’s plagued with a few drawbacks, such as poor resistance to ozone, sunlight, and weather. It also has limited resistance to high temperatures and flames.
In the mechanical world, where machinery and equipment make the earth move and gears rotate, the oil seal is an important component. Oil seals, or shaft seals, are a crucial part of various industrial equipment and applications, ensuring that lubricants don’t escape and contaminants don’t enter. While they may seem simple, their construction, design, and application are anything but. This in-depth guide aims to help you understand the essential role of oil seals, their construction, the various designs available, and key factors to consider when selecting one for your application.
O-Rings
Modern engine concepts, like higher engine speeds and oil temperatures, longer intervals between oil changes and lubricants with modern additives, require new solutions for dynamic seals. They have to withstand the high loads lastingly. PTFE technology is the answer, since it perfectly meets these demands.
