4.2L V8 Audi RS4 & RS5 Seal for high-pressure pump BAR-TEK®
Replacement shaft seal for the high-pressure pumps of your 4.2L V8 Audi A8, RS4 or RS5. If you want to upgrade your high-pressure pump, we also recommend replacing the seals. Our shaft seal ensures reliable sealing. Leaking shaft seals on the high-pressure pump can also be a problem for production vehicles. This can result in bearing damage due to oil thinning. It is therefore advisable to check these regularly. Replaces the sealing ring of the pump with the OEM part numbers 079127029AL and older revisions. One seal is supplied.
