Abstract: A container (10) for a filter (12) has a cylindrical housing (16) receiving the filter (12) and permitting replacement of the filter (12) from an open end. An enlarged diameter fitting (22) is secured about the open end of the cylindrical housing (16) and has retaining lugs (30) for retaining a removable end cap assembly. The removable end cap assembly has an anchor plate (40) with projections (46) that are received within arcuate slots (32) of the end fitting (22). The anchor plate (40) is coupled to an end cap (42) for rotation to position the projections (46) beneath the lugs (30) to restrain outward movement of the anchor plate (40). A single bolt (44) through the end cap (42) is threaded to the anchor plate (40). Rotation of the bolt draws the anchor plate (40) tightly against the lugs (30). The end cap (42) is simultaneously forced against an O-ring (36) disposed on the outer end (50) of fitting (22) for sealing the end cap to the container. An embodiment of FIG. 5 has an adaptor (25A) removably connected to a flange (22A) on the cylindrical housing (16A) to provide a retrofit. An embodiment of FIGS. 6-9 provides visible external indicia on the cap assembly to indicate when the cap (42B) is in fully engaged position with the housing (16B).

Abstract: A fluid containing system, as in a filter, for toxic or hazardous fluids is provided with rotatable base seals that can be alternatively positioned to permit the flow of fluids from the filter supply line, passing through the filter or, alternatively, the filter supply line can be sealed shut to prevent fluid leakage when the filter is removed. A third filter seal position is provided, wherein a cleaning fluid, for example compressed air, can be supplied to the filter in order to remove excess fluid from the filter prior to removal. An alternative embodiment permits removal of the filter and sealing of the supply line by rotating the filter and seal assembly about the supply line access to save space or to facilitate changing the filter. The fluid containing system can also function as a fluid sampler, or to add materials to the fluid system.
