The Rebco ROTXN Lock Mandrel is the No-Go counterpart to the ROTX, featuring chamfered Keys and accepting a Bottom Sub to convert it to a full No-Go lock. It is designed to land in a ROTXN Landing Nipple of the same size, covering the identical bore range as the ROTX, from 1.250" through 4.562". Without the Bottom Sub, the ROTXN can also function as a selective lock, giving it the same dual-mode flexibility as the ROTRN.

The same product code structure applies: Product Code 10 for standard sizes up to 2.875"; Product Code 18 Safety Spring for 3.313" through 4.562"; and Product Code 17 Interference Hold Down for 1.875" and 2.313" seal bores. The Safety Spring feature and Shear Pin function identically to those in the ROTX Safety Spring variant, with the Shear Pin lodging between the Expander Sleeve and Key Retainer once the lock is set in the nipple. The ROTXN shares the same running and pulling tool family as the ROTX, and Check Set Tools (Product Code 41) are also available for all ROTXN sizes.

How to Order: Product Code 10 (standard, 1.250" to 2.875"), Product Code 17 (Interference Hold Down, 1.875" and 2.313"), or Product Code 18 (Safety Spring, 3.313" to 4.562"). Specify the nipple seal bore size, material, service conditions, and whether a Bottom Sub is required for the No-Go configuration.
