Stinger

Large through bore makes it ideal for wash strings

The Caledyne Stinger is designed to engage with a shifting profile in a downhole tool. The spring-loaded keys collapse through restrictions and fully expand to engage the relevant profile. Once the tool has been shifted, the keys auto release from the profile. The tool has a shear out facility in the event that the downhole tool cannot be actuated. The large through bore allows for fluid to be circulated through the tool, making it ideal for use on wash strings.
