Oil Seal.

The seal runs against a rotating shaft to retain lubricant within its housing while excluding dirt and moisture. Once the lip hardens or wears it allows lubricant to weep past the shaft and lets contaminants in, so the seal is renewed whenever the assembly it serves is dismantled.

Frequently asked questions

What does the AEU4042 oil seal do?
The AEU4042 is an engine oil seal that runs against a rotating shaft to retain lubricant inside its housing while keeping dirt and moisture out.
When should this oil seal be replaced?
It's renewed whenever the assembly it seals is dismantled, since removing the housing usually ages the seal's lip. Once the lip hardens or wears it lets oil weep past the shaft and lets contaminants in.
Can this oil seal be reused after removal?
These are typically single-use once the housing has been apart. Reusing it risks the lip no longer sealing evenly against the shaft, leading to a slow oil leak.
