A device for connecting a fluid conduit to an orifice of a vessel includes a flexible fitting, a deformable fitting, and one or more compression fittings. The flexible fitting can fix a position of the fluid conduit with respect to the orifice of the vessel, and the deformable fitting can provide a fluid seal between the fluid conduit and the orifice of the vessel. A method for connecting a fluid conduit to an orifice of a vessel includes urging a deformable fitting against both a surface of the fluid conduit and the orifice, urging a flexible fitting toward a surface of the fluid conduit, and attaching the flexible fitting to the orifice.
