Donaldson Lube Head Assemblies

A lube head assembly is the mounting head an engine oil filter threads onto, carrying the ports, the sealing face and normally the bypass valve. It stays with the engine while filters are changed against it, so a damaged sealing face shows up as a leak that a new filter will not cure.

Heads are matched to a filter thread and port arrangement. Search by Donaldson part number, or send us the number from the existing head.
