Abstract
A dual-flow lubricant filter assembly having a bypass filter element with a full-flow filter element stacked thereon includes a grommet disposed between the filter elements for isolating lubricant streams after the lubricant has passed through the filter elements. The grommet is molded of a resinous material and includes an external flange which is sandwiched between the bypass and full-flow filter elements in order to axially position the grommet. The grommet also includes an internal flange which seals with an unthreaded portion of a standpipe with which the filter assembly is coupled.
