An apparatus for removing an obstruction within a pressurized fluid service pipeline which includes a flexible rod; a module for connecting to the service pipeline in which the module defines a channel and a first opening in which the first opening communicates with and between the service pipeline and the channel and permits the channel to receive the pressurized fluid from the pipeline in which the module defines a second opening which communicates with and between the channel and an outside of the module; and a flexible seal in which the seal defines an opening and in which the seal is positioned to abut the module and align the opening of the seal with the second opening for receiving the insertion of the flexible rod through the opening of the seal to engage the obstruction in the pipeline, in which at least a portion of the flexible seal engages the flexible rod inhibiting the pressurized fluid in the channel from moving along the flexible rod to the outside of the module, and in which at least a portion of the flexible seal is flexed against the flexible rod further inhibiting the pressurized fluid from passing from the channel along the flexible rod to the outside of the module. A method is also employed to remove obstructions within a pressurized fluid service pipeline.
