Abstract

La présente invention concerne un outil de sertissage ou de compression qui comprend deux éléments de mâchoire reliés de façon pivotante qui peuvent être tirées de façon sélective l'une vers l'autre afin de sertir ou autrement comprimer un raccord sur un tuyau ou une autre pièce. L'outil utilise un assemblage de serrage qui permet l'application de forces de rotation dirigées de façon opposée pour ainsi empêcher, ou au moins sensiblement réduire, le potentiel de transmission de moments de couple indésirables dans le tuyau ou la pièce.
