FILTRATION ASSEMBLY INCLUDING ABUTTING FILTRATION ELEMENTS WITH END CAPS FORMING COMMON ANNULAR GROOVE

摘要

A filter assembly (10) including a first (12) and second (14) filtration element positioned in an abutting end-to-end arrangement along a common axis (X). Both filtration elements (12, 14) include a cylindrical housing (16, 16′) enclosing a filtration media and extending along the axis (X) between opposing ends, and an end cap (18, 20, 18′, 20′) located at each of the abutting ends of the filtration elements (12, 14) and comprising an annular surface (28, 28′) co-extensive with the housing (16, 16′) and an annular stepped edge (29, 29′). The first (12) and second (14) filtration elements are positioned with their end caps (18, 20′) directly engaged with each other so that the stepped edges (29, 29′) collectively form a continuous annular groove (31) about the periphery of the filter assembly (10). The annular groove (31) provides an effective means for handling filtration elements without increasing the overall length of end cap.
