Abstract
Cartridge components are configured to trap the upper end of a concave housing portion to define an enclosure surrounding a filter element. A disclosed embodiment includes a concave metal housing portion and plastic cartridge components, but other materials may be employed. An upper end cap spans the open end of the housing portion and defines at least one fluid flow aperture. A retainer surrounds the housing portion and is secured to the first component, with engagement features on the housing portion trapped between the upper end cap and retainer. The upper end cap and retainer may be secured to each other by spin welding, threads, adhesive or other suitable means. The outside circumference of one or both of the upper end cap and retainer may be provided with lugs, threads, bosses or other features to interface with complimentary features on the head for securing the cartridge to a head.
