[54] FLUID-FREE HYDRAULIC CONNECTOR
[57] Abstract: Certain aspects and features of the disclosure relate to a hydraulic connector for use in a wellbore, for example, with or as part of a disconnect tool. The hydraulic connector can isolate hydraulic fluids in upper and lower hydraulic lines using hydraulic pistons. The pistons in the upper and lower parts of the hydraulic connector interconnect mechanically when the connector is engaged and communicate pressure without transferring hydraulic fluid across the interface. The hydraulic fluid can therefore remain confined within the upper and lower hydraulic lines even when the disconnect tool is disengaged, reducing or eliminating incidents of hydraulic fluid leaking or spilling into the wellbore.
