The Rebco XNH and XOH Instrument Hangers are the ROTX-family equivalents of the RNH and ROH, respectively, designed to deploy recording instruments into ROTXN and ROTX Landing Nipples. Like the RNH/ROH, both the XNH and XOH are built on a Lock Mandrel Assembly with a Protector Sleeve in place of a Seal Stack, the same no-seal, sleeve-protected design that minimizes wear and simplifies repeated survey operations.

The XNH and XOH cover an even broader size range than the RNH/ROH, starting from a smaller minimum nominal size of 1.900", making them available for smaller-bore completions where the ROTRN/ROTR nipple profile is not present. They extend through to 5½" nominal, covering seal bore sizes from 1.500" to 4.562". The dedicated running and pulling tools are the ROTX Running Tool (Section III) and the ROTGR Pulling Tool (Section IV), selected by nominal size and seal bore size. All assemblies are manufactured from normal alloy in accordance with NACE MR-01-75 standards.

How to Order: Specify XNH (for ROTXN nipples) or XOH (for ROTX nipples), nominal size, seal bore size, and box thread connection (Amerada ¾"–16 or Sucker Rod 15/16"–10). Contact Rebco for non-standard sizes and alternative materials.
