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.
Polyacrylate Oil Seals - Mostly selected for automotive and transmission uses, polyacrylate seals are able to withstand fuel, oil, ozone, sunlight and weather when used. With cars exposed to all these different fluids and elements, they are the perfect choice. However, they should not be used in low temperatures, as their flexibility weakens when cold.
Rubber O.D. wall type Provides stable sealing performance around the seal O.D. surface.
When installing a new valve cover gasket, it is essential to ensure that it is the correct size and type for your engine. Using the wrong gasket can result in leaks and other issues. Additionally, proper installation is crucial to ensure that the gasket seals properly. This may involve cleaning the surfaces where the gasket will be installed and applying a sealant to help prevent leaks This may involve cleaning the surfaces where the gasket will be installed and applying a sealant to help prevent leaksERIKS type GV (type C according to DIN) is equivalent to type M, but is a heavy-duty version with a double metal casing. This can be a useful solution with larger diameters in more demanding applications. There is also a version of this type with a dust lip; the GVST (type CS according to DIN).
Heat and attrition are generated by the parts moving against each other. The sealing function can only be ensured if an intentional defined leakage of oil is able to exit for seal lubrication, preventing seal wear and possible failure, while a tight static seal between shaft and sealing lip must be assured when the shaft is stationary.
Silicone gasket sheets are equally at home in the construction sector, where they serve as weatherstripping around windows and doors, preventing drafts and reducing energy loss Another important consideration when selecting a hub oil seal is its compatibility with the fluid being sealed

Most oil seals consist of some basic elements that configure their structure, such as the sealing element, the metal case, and the spring:
Moreover, rubber flange gaskets offer ease of installation and removal, which reduces downtime and maintenance costs. They are also relatively inexpensive compared to other sealing solutions, making them a cost-effective choice for many applications.The metal used in the outer case of oil seals is usually made of carbon steel. Upon request, and depending on quantities, a different type of steel (such as stainless steel) can be used.

The spark plug is an essential component of any combustion engine, including those found in scooters and motorcycles equipped with the popular GY6 engine. The GY6 spark plug plays a critical role in igniting the air-fuel mixture in the combustion chamber, which in turn powers the engine to propel the vehicle forward. Manufactured from high-quality elastomers, rubber U-channel gaskets boast exceptional elasticity and resilience, enabling them to conform to the shapes of the mating surfaces while withstanding the pressure differences that arise in industrial environments. This adaptability is further enhanced by the material's inherent ability to resist degradation from oils, chemicals, and temperature fluctuations—a vital attribute given the diverse conditions under which they operate.This technique is used when the seal depth must match the housing surface precisely. It involves stopping the installation tool at the machined housing face. Ensure the tool is perfectly perpendicular to the shaft for best results. This technique is ideal for applications requiring exact seal positioning relative to the housing face.
