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.
- Another important consideration when selecting spark plugs is the heat range. The heat range of a spark plug refers to its ability to dissipate heat from the combustion chamber. Choosing the correct heat range is crucial to prevent engine damage and ensure optimal performance. It is recommended to consult your vehicle's owner's manual or a professional mechanic to determine the appropriate heat range for your car.
Oil Seals Enable Your Equipment to Operate Efficiently
Standard 3760/3761
Seals perform much better and longer when they are continuously lubricated with an oil that has the correct viscosity for the application and that is compatible with the seal lip elastomer material. The consideration of seal incompatibility, particularly with certain additives and some synthetic lubricants, should not be ignored, but unfortunately very often is.
The perfect solution to this is to always use an oil seal that fits properly; the right size of the seal should be used. And in other cases, backup devices should be used to avoid the buildup of clearance gaps within the mating edges.
Remove the pump fixing nuts or bolts. Pull the pump and gasket or gaskets off the engine.

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.
