Selecting Quality Auto Gaskets and Head Gaskets
Oil Seal Materials
The intake valve cover gasket is a vital component that ensures the proper sealing of the intake valve cover, preventing oil leaks and maintaining the integrity of the engine's intake system. This gasket is essential for maintaining the efficiency and reliability of the engine, contributing to optimal engine performance and longevity.
Generally, oil seals vary in materials and types based on the corresponding application. Common materials include:
Reinforced GVP design for larger diameters, with rotation speeds of up to 15 m/s and pressure of 3-4 bar
Furthermore, neoprene foam gaskets offer superior insulation properties
. The foam material has a low thermal conductivity, which helps to reduce heat transfer and maintain temperature control in applications where thermal insulation is critical. This makes neoprene foam gaskets suitable for use in HVAC systems, refrigeration units, and other applications where thermal management is essential.neoprene foam gasket

Because the inner diameter of the oil seal must be stretched during assembly, it is necessary for the shaft to possess a ramped edge. The angle at which the ramped taper should be chamfered is 30° a 50°. If a flange or keyway is present on the shaft, it is best to use a bushing. The bore should also have a chamfer of 30° over at least 1 mm on the ramped side. Be sure to round off the edges properly in the process.
Installation of the oil seal

Is the seal you need not available from one of our standard ranges? No problem. We design and supply seals in any material, size and quantity - from very small to very large volumes.

oil seal types. Labyrinth seals are designed to provide a barrier to the leakage of oil by creating a tortuous path for the oil to flow through. V-ring seals, on the other hand, are designed to provide a more dynamic sealing solution by conforming to the shaft, thus preventing oil leakage.
Oil seals are one of the major contact type sealing devices.
• They prevent leakage of the lubricant or other sealed substance, and
• prevent entry of dust and foreign matter (dirt, water, metal powder, etc.) from outside.
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
