The Rebco ROTE and ROTK are Bottom No-Go Lock Mandrel Sub-Assemblies, the large-bore counterparts to the ROTF and ROTM, designed for use in BR Landing Nipples with seal bores ranging from 2.750" to 3.812". As with the ROTF and ROTM pairing, the ROTK is essentially the ROTE sub-assembly without the Packing Unit and Packing Mandrel; the ROTE includes the full Packing Unit for pack-off applications. Both feature internal Fishing Necks providing large flow areas, and Collet-type locking fingers paired with Bottom No-Go shoulders to resist movement in both directions once set.

Available in nominal 3 1/2" tubing (seal bores of 2.750" and 2.812") and nominal 4 1/2" tubing (seal bores of 3.688", 3.750", and 3.812"), the ROTE and ROTK share the same ROTGS Running/Pulling Tool and ROTM-specific prong used for the ROTF and ROTM family, keeping tool requirements consistent across the larger bore lock range. All sizes are constructed from Norm Alloy, and a variety of alternative materials are available for specific downhole conditions.

How to Order: Product Code 10. Specify lock type (ROTE for pack-off, ROTK for no pack-off), nominal tubing size (3 1/2" or 4 1/2"), seal bore size, thread type (Box for ROTE, Pin for ROTK), and material.
