    Abstract: The invention relates to a sealing device of a system for sealing a fluid passage from a first component (1) to a second component (2), comprising at least one first sealing element (3) which is of an annular design to allow fluid to pass through it, includes at least one expansion slot (4) and has a first sealing surface (5) sealingly associated with the first component (1) and has a second sealing surface (8) sealingly associated with the second component (2), said at least one first sealing element (3) being flexible and said expansion slot (4) being designed in such a way that radial and resultant axial pressure of the fluid passing through there will cause the first sealing element (3) to expand in the radial direction and thus press radially in the direction against the first component (1), with said first sealing surface (5) with the expansion slot (4) being sealed against the first component (1) by abutment in the direction of the latter, and in such a way that the first sealing element (3) will press axially in the direction against the second component (2), with the second sealing surface (8) with the expansion slot (4) being sealed against the second component (2) by abutment in the direction of the latter.

    Abstract: A drain protector (1) is provided which has a conformable bottom frame (3) having a central opening that is closed by a filter element (4) spanning the opening. The filter element is capable of removing silt from water on a building site. The bottom frame is capable of conforming to the surface terrain around a drain opening due to the compressive weight of the drain protector in-situ. There is a porous top frame (2) that provides additional separation for debris from silted water and also provides compression weight for the bottom frame. The drain protector (1) may be removed, cleaned and reused.

    Abstract: A filtration filter device that enables the sealability of a fluid channel to be improved is provided. A filtration filter device according to the present invention includes a first channel-forming member that has a first channel through which a fluid flows inside thereof, a second channel-forming member that has a second channel through which a fluid flows inside thereof, and a filtration filter that extends across the first channel or the second channel and that filters an object to be filtered that the fluid contains. The first channel-forming member includes an external thread. The second channel-forming member includes an internal thread. The first channel-forming member and the second channel-forming member have respective inclined surfaces that incline with respect to a screw direction in which the external thread is screwed into the internal thread at positions nearer than the external thread and the internal thread to the first channel or the second channel, and the inclined surfaces are in contact with each other with the external thread screwed in the internal thread such that the first channel and the second channel are in communication with each other.
