Abstract
The invention relates to a novel tubular fitting member formed of a deformable material, such as steel, which may be combined with a helically wrapped wire screen to produce a mechanical seal of a gap formed adjacent the cut-off end portion of the screen when the screen is cut off perpendicular to its supports. Such cutting produces a loose, tapered wire tail which is normally broken off, thereby producing an open gap in the screen which is wider than the width of the slot between the wire wraps. The tubular fitting member has a groove formed in its outer surface closely adjacent to the screen end of the fitting. The groove defines the inner wall of a deformable flange which may be selectively forced toward the screen to close any gap formed adjacent its end during the cut-off operation.
