Locking Mandrels

No oil or gas worksite is complete without a diverse selection of locking mandrels. These unique devices enable you to connect various tools and equipment down your wellbore. As the downhole gets deeper and deeper, you'll need even more locking mandrels to keep everything safely and securely in place. 

Locking mandrels, often simply called locks for short, anchor onto the tubing string, giving you a stable foundation to mount a variety of downline equipment, including chokes, valves, plugs and more. For each type of tool, there are specialized locking mandrels, so it is important to choose the right device for the task at hand.
