The R Lock Mandrel is a selective lock which can be installed in the chosen R landing nipple in a series of R nipples. It has retractable keys with straight shoulders and an integrated packing mandrel that allow the tool to lock into a profile nipple and create a seal. This allows the lock to create or hold pressure from above or below based on the equalizing assembly being used.
The RN Lock Mandrel is the non-selective version of the R Lock Mandrel. The keys have angled shoulders, and the lock is designed to stop against the No-Go diameter at the bottom of an RN Nipple. The RN lock is used in single installations in the bottom RN nipple in a series of R profile nipples. RN Locks have a higher pressure from above rating than R locks of the same size.
