Abstract
A spin-on filter includes a baseplate secured to an end cover and further includes a filter element disposed in a canister having an open end. The end cover is secured to the open end of the canister by seaming a flange formed at the edge of the end cover with a flange formed at the end of the canister. An end cap which is secured to the filter element is trapped between the baseplate and the seamed flanges, thereby securing the filter element in the canister and avoiding the need of a helical spring for urging the filter element toward the baseplate.
