ABSTRACT:
A fluid-tight sealing slide fastener includes a pair of rows of coupling elements mounted respectively on inner opposite edges of a stringer tape, an elastomeric top stop mounted on the stringer tape around a terminal opening at ends of the rows of coupling elements, and a slider for taking the rows of coupling elements into and out of intermeshing engagement. The slider includes a slider body having a pair of upper and lower plates interconnected by a diamond, a presser having a plurality of pins extending through the upper plate, and a screw having a threaded shank threaded in a cylindrical body on the upper plate of the slider body and a head acting on the presser. When the slide fastener is closed and the screw is tightened, the pins are pressed against the top stop which is resiliently pressed against the lower plate and the diamond of the slider body to provide fluid-tight sealing between the top stop and the slider.
