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.

Dependent claims

A fitting for sealingly engaging an inlet having an outer surface, the fitting comprising:

a housing comprising a base and a closure;
said closure having a first aperture for receiving the inlet therethrough;
said base and said closure threadably coupled together to define a cavity within said housing;
a piston disposed within said cavity for sliding movement therein;
a resilient bushing disposed in said cavity between said closure and said piston, said resilient bushing having an inner diameter aligned with said first aperture;
a fluid passage through said housing for providing fluid to the inlet when the inlet is coupled to the fitting;
and
a locking member threadably coupled to said housing and configured to prevent damage to said base and said closure;
the fitting having a first condition wherein the inlet can be received within said inner diameter of said bushing, and having a second condition wherein said piston axially compresses said resilient bushing against said closure and said resilient bushing radially expands to engage the outer surface of the inlet.
