The metal case and spring material used in the oil seal should be selected based on the substance to be sealed.
Table 6 shows how to select the metal case and spring materials.
Most conventional oil seals are designed only to withstand very low-pressure applications (about 8 psi or less). If additional internal pressure is present or anticipated, pressure relief is necessary.
The correct installation of an oil seal is also crucial for its long-term performance. Improper installation can lead to damage to the seal, reducing its effectiveness and potentially causing leaks. It is essential to follow the manufacturer's instructions carefully when installing an oil seal to ensure that it is properly seated and aligned.
