Table 2: How to select the seal type

If you are installing an o-ring to serve as a backup, make sure you put it on the low-pressure side of the system. This will make the high-pressure side push the o-ring against the backup.

The metal case serves as the oil seal’s exterior or frame, providing rigidity and strength to the seal. The case material selection depends on the environment in which the seal will operate. Often, the same rubber material used in the seal element covers the case to help seal the exterior of the oil seal in the housing bore.
