Abstract: Filter elements and filter systems are provided. The filter element allows for a reversed flow of fluid through the filter element when flowing from a first port to a second port of a filter head of the filter system. The filter element includes a standpipe in a central cavity of a tube of filter media that is fluidly connected with an exterior of the tube of filter media by a radial flow conduit and an axial flow tube.

Abstract: A liquid filter in the form of a filter element or a filter cartridge provides torsion locking relative to a filter head when the housing of such filter is threaded onto a filter head. Many embodiments employ a filter that includes a nipple portion at a top end with the torsion lock detent provided outboard of the nipple portion or integrated into the nipple portion. Many embodiments employ a simplified shoulder transition region at the top end of a torsion locked filter element. Valve actuation and/or filter differentiation is used in some embodiments. Different torsion locking arrangements, deformable thread profiles and other liquid filter features are disclosed.
