It fits Eaton heavy-duty truck axles, specifically the DS/DD 461, 521, and 581 series. The seal prevents gear oil from leaking out of the differential housing around the pinion shaft, ensuring the internal components stay properly lubricated. It is typically replaced when a leak is noticed at the pinion flange or during a differential rebuild.
