The Rebco ROTD is a Collar Lock Mandrel Sub-Assembly designed to be set in API Tubing Collars in wells that do not have Landing Nipples, covering nominal sizes of 2", 2 1/2", and 3". The lock body's Dogs engage the inner profile of the API tubing collar to anchor the mandrel in place. A separate ROTD Element Assembly is then added to seal off the tubing bore, and a variety of sub-assemblies can be combined with the ROTD to suit the specific application; the assembled configuration is capable of holding pressure differentials in both directions.

The ROTD Element Assembly is available separately as a Redress Kit (Product Code 310), allowing worn or damaged elements to be replaced in the field without discarding the entire lock sub-assembly. Running is performed with the ROTDO Running Tool, and retrieval is performed with the ROTGSL Pulling Tool. All sizes are constructed from Norm Alloy.

How to Order: Product Code 10 for the ROTD Collar Lock Mandrel Sub-Assembly; Product Code 310 for the ROTD Element Assembly (Redress Kit). Specify nominal size (2", 2 1/2", or 3"), material, and the type of accessory sub-assembly required for the intended application.
