LIQUID FILTER HAVING INTERCHANGEABLE SPIN-ON CANISTER FILTER AND CARTRIDGE FILTER, AND METHODS

摘要

A liquid filter assembly includes a filter head (44) having an interchangeable spin-on canister filter (46) and a bowl-cartridge filter (48). Methods of using the liquid filter assembly include providing a filter head capable of operably receiving both a spin-on canister filter and a bowl-cartridge filter. The method also includes operably installing one of the spin-on canister filter and the bowl-cartridge filter onto the filter head (44) to provide a filter assembly. After a period of use, the spin-on canister filter or bowl-cartridge filter is removed and replaced. The replacement can include, interchangeably, a spin-on canister filter and a bowl-cartridge filter. Constructions for accommodating an interchangeable system include preferred arrangements of mechanical connection structure.
