About this product
When shaft seal differential performance matters, the CEI 139.891 delivers — built to the same dimensional and material standards as the original part it replaces. This part supersedes original equipment references: 12019701, 139.891, 139891000, 35658 and 6 more. Matching these numbers confirms a like-for-like replacement with no loss of function. CEI is a recognised supplier of automotive replacement components to independent workshops and dealer networks across Europe. All parts are sourced from authorised distribution channels and carry full manufacturer traceability — you receive exactly the same component supplied to professional garages and dealer workshops.
