The ‘P-X’ Lock Mandrel is a down hole device, run and retrieved on slick line in which it is placed and anchored to the ‘P-X’ or ‘P-XN’ Landing Nipple within the tubing string to pro- vide a setting point for flow-control equipment such as valves, chokes and plugs.

The two main types of Lock Mandrel use different mean of locating and anchoring; a Selective Lock locates and anchors any matching landing nipple profile within the tubing; and a No-Go non-selective nipple lock, usually installed at the bottom of the tubing string. The No-Go nipple lock can also be used in taper string application.
