Abstract
A coupling system for maintaining an end of a tube in substantially sealed alignment within an aperture in a wall, in which the tube is held by a clamp member affixable to the wall adjacent the aperture. A tube end is provided which is formed by a first tube tip member and a second tube tip member which fits concentrically around the first tube tip member. The second tube tip member has a wall thickness substantially less than that of the first tube tip member, and has a radially outwardly projecting annular bead formed thereon. The first tube tip member and the second tube tip member are affixed to each other, but limited axial movement of a portion of the first tube tip member relative to a portion of the second tube tip member is permitted.
