HR／HRN PROFILE LOCK MANDREL

The HR/HRN Locking Mandrel is a selective lock that can be installed in the HR/HRN Landing Nipple. They are used in heavier weight tubing due to higher well pressure. These locking mandrels use keys that lock into a profile in the landing nipple that allow it to hold pressure differential from either above or below. This lock can be used in conjunction with pump through plugs, positive plugs, safety valves, and standing valves.

Other sizes, connections and material options available upon request.
