Abstract:
1. A push plug for sealing an open end of a cable-carrying conduit, comprising: a distal end, a proximal end, a neck, a body, and a cap aligned along a longitudinal axis; said neck disposed between said cap at a distal end and said body at a proximal end; said plug proximal and distal ends, the proximal plug end being adapted for insertion into the conduit open end; said plug body including an annular ridge adapted for forming a seal with the conduit and resisting removal from the conduit; a cable passage extending from and open at the proximal end towards the distal end; a cap at said plug distal end, said cap including a membrane with a closed, intact configuration closing the passage and a penetrated configuration penetrated by the cable; said membrane in the closed configuration providing a substantially fluid-tight seal of the passage at the plug cap; said plug passage being adapted to receive the cable in the penetrated-membrane configuration with the cable extending through the membrane and the membrane forming a substantially fluid-tight seal between the cable and the plug; and wherein said passage comprises two oblong rounded-rectangle passages tapering from a larger opening at the proximal end to a smaller opening at the distal end, two circular passages running alongside said two oblong passages, the circular passages including a distal diameter D
