Abstract
A disposable two-stage spin-on liquid separating device having particular use for separating water from hydrocarbon fuels. The device includes an outer casing having an open upper end which is enclosed by a cover assembly. The cover assembly includes a liquid inlet conduit and a liquid outlet conduit with one of said conduits being located axially of the cover assembly and having a threaded connection for attachment to a liquid flow system. Located within the casing is a two-stage separating unit composed of a coalescing assembly and a separator stage which is located downstream of the coalescing assembly. The coalescing assembly includes a coalescing element and upper and lower end caps are secured to the ends of the element. The peripheral edge of the upper end cap extends radially outward and is secured to the upper end of the separator stage. Attachment of the cover assembly in the casing acts to clamp the separating unit between the cover assembly and the bottom of the casing.
