Cosasco RSL Retriever is a precision tool which allows safe, easy insertion and removal of various equipment and tools through a Cosasco Access Fitting, without de-pressurizing the pipeline or vessel.
Used in conjunction with a Cosasco Service Valve, system pressure is safely ported into the tool which allows the valve to be opened and the retrieval operation to be performed. Rotation and translation in and out of the fitting is controlled by two adjustable handles. No movement or telescoping of the tool body is necessary, requiring less clearance area than standard retrievers.
To ensure safe working practices, a Back Pressure Pump must be used with all Cosasco Retrievers when pressure equalization is not achieved by normal operating procedures. Pressure equalization is crucial to ensure safe removal of the plug assembly from the access fitting.

The Cosasco Magnetic Swab Assembly (Cosasco part number 121870) is a retrieval accessory used in conjunction with the Cosasco Hot Tap Tool, to remove hot tap cuttings from an access fitting before installing a device. If proper procedures are not followed during the swab operation, the Swab can potentially become detached from the retriever.
