Description

The Flow Release External Pulling Tool (JDC) is a cost-effective means of engaging, latching and manipulating standard, external fishing necks.

The tool can be utilised by setting down weight to engage the external fishing neck allowing the weight applied to the tool to overcome the internal spring force.  If the device cannot be recovered using this method, circulation can be initiated allowing flow through a nozzle fitted in the core of the tool.  This creates an internal pressure that activates an unbalanced piston thus allowing the catch grapple to become de-supported and pass into the internal fishing neck profile.  This method also allows for jetting to clean the fish neck profile.
