Abstract: A fitting for sealing against the outer surface of an inlet includes a housing comprising a base and a closure defining a cavity within the housing. A resilient bushing is disposed within the cavity and is positioned between the closure and a piston slidably disposed in the cavity. The fitting has a first condition wherein the inlet can be received within an inner diameter of the bushing through an aperture in the closure. The fitting can be actuated to a second condition wherein the piston axially compresses the resilient bushing against the closure, thereby causing the inner diameter of the bushing to expand radially inwardly to sealingly engage the outer surface of the inlet. When the inlet is sealingly engaged by the resilient bushing in the second condition, fluid may be admitted to the inlet through a fluid passage in the housing.
