A sealing assembly for forming a seal about an elongate object includes a resilient seal member and a loading mechanism. The resilient seal member includes an inner wall surface defining a channel to receive the elongate object. The seal member has first and second opposed sides. The loading mechanism includes a first pressure member on the first side of the seal member; a second pressure member on the second side of the seal member; a biasing member on the second side of the seal member and interposed between the seal member and the second pressure member; and an adjustable displacement mechanism accessible and operable from the first side of the seal member to displace the first and second pressure members relative to one another to selectively apply a compressive load to the seal member such that the inner wall surface is expanded inwardly to exert a sealing pressure on the elongate object.

L'invention concerne un élément d'étanchéité pour former un joint d'étanchéité autour d'un objet allongé, comprenant un élément d'étanchéité élastique et un mécanisme de chargement. L'élément d'étanchéité élastique comprend une surface de paroi intérieure définissant un canal destiné à recevoir l'objet allongé. L'élément d'étanchéité a des premier et second côtés opposés. Le mécanisme de chargement comprend un premier élément de pression sur le premier côté de l'élément d'étanchéité ; un second élément de pression sur le second côté de l'élément d'étanchéité ; un élément de rappel sur le second côté de l'élément d'étanchéité, et interposé entre l'élément d'étanchéité et le second élément de pression ; et un mécanisme de déplacement ajustable accessible et opérationnel à partir du premier côté de l'élément d'étanchéité pour déplacer les premier et second éléments de pression l'un par rapport à l'autre afin d'appliquer sélectivement une charge de compression à l'élément d'étanchéité, de telle sorte que la surface de paroi intérieure est dilatée vers l'intérieur pour exercer une pression d'étanchéité sur l'objet allongé.
