Abstract
Durante la expansion radial provocada por el paso de una bala en el interior de la union tubular, los espaldones inclinados formados respectivamente sobre una superficie periferica del elemento hembra que mira radialmente hacia el interior y sobre una superficie periferica del elemento macho que mira radialmente hacia el exterior experimentan un desplazamiento axial con relacion al otro para estar en contacto mutuo sellado con interferencia radial.
