Abstract: A remotely-operated fluid connection assembly to hold higher internal pressures in larger diameters. The assembly comprises a fluid connection adapter and a fluid connection housing assembly. When the adapter enters the housing assembly: (A) locking elements on the housing assembly constrict about the adapter; and (B) at least a first seal section on the adapter sealingly contacts a first seal bore on the housing assembly. Progressive engagement of a locking ring upon the locking elements urges the locking elements to tighten against the adapter. Internal pressure encourages adapter displacement, which then further tightens the adapter against the locking elements as now restrained by the locking ring. Internal pressure further encourages the first seal section on the adapter to expand radially to tighten the contact with the first seal bore in the housing assembly.

Abstract: A remotely-operated fluid connection assembly to hold higher internal pressures in larger diameters. The assembly comprises a fluid connection adapter and a fluid connection housing assembly. A first seal section on the housing assembly sealingly contacts a first seal bore on the adapter when the adapter enters the housing assembly.
