Abstract
An improved seal at the junction of a pipe or tube to an opening formed in a flat wall or in the wall of a cylindrical or rounded container, including axially tapered exterior and interior peripheral surfaces. The tapers of such surfaces being different one from the other and being of such a degree that, when the seal is inserted into the opening in the receiving member and the pipe is inserted therethrough, the material from which such seal is fabricated is forced to bulge around the periphery of the opening, thereby securing the pipe in the opening and perfecting the seal therebetween.
