First, wash your hands before handling the oil seal. This is because dirt on the sealing surface or oil in fingerprints can compromise the integrity of the seal, while small particles can cause wear and tear, damaging the sealing surface and leading to leaks.

Finally, ensure that your equipment is clean. This is because dirty equipment can affect the effectiveness of the oil seal.
