ABSTRACT:
A housing system for a removable filter cartridge in an automotive lubrication system. The housing is formed of a thin-walled sheet metal drawn cylinder, with end removed, to form an elongated cylinder with both ends open. A base end has a formed metallic base secured therein by a rolled flange in the sheet metal housing. A closure end has a formed threaded ring secured to the end thereof by another rolled and swaged connection between the sheet metal and formed ring. In the preferred embodiment, the base carries permanent center tubes, and the filter cartridge is of unsupported construction, containing no metallic supports, and adapted to be disposed of in an environmentally acceptable manner.
