摘要:
A filter includes a housing having a cavity. A media pack, which includes a filter media, is arranged within the cavity and includes a central opening extending between opposing ends of the media pack. A center tube is arranged within the central opening and extends out of the central opening beyond one of the ends to provide a first end. A relief valve is supported on the first end. The filter cartridge assembly is installed into the housing with the relief valve in sealing engagement with a tapping plate of the housing. The relief valve performs the function of a seal between the filter cartridge assembly and the tapping plate in addition to performing pressure relief functions.
