In order to use the oil seal reasonably, the following points should be paid attention to:
-
Smear a little gasket sealant round the cover flange and fit the new gasket to it. Make sure it is flat and straight.
-
-
- Spring Back: The rubber-covered OD of the seal may have elastic memory, causing it to retract from the installation point after being pressed in. Ensuring the bore is clean and provides sufficient friction helps prevent spring back.
-
- The 20mm thickness provides an excellent balance for many applications; it is thick enough to withstand moderate pressures without being so bulky that it interferes with the assembly of parts. In automotive applications, these gaskets may be found between engine components, ensuring oils and coolants remain where they should, protecting against leakage and subsequent damage.

Based on the above flowcharts, the oil seal type that meets the requirements shown in Table 3 would be the type code MHSA or HMSA shown in Table 4.

Rubber type
This is almost similar to that of ‘A’ type seal. But this has the metal case placed outside. When the housing is rough, temperature is high and working conditions are severe, this type is preferred
