The Rebco ROTRZB Instrument Hanger is specifically designed to land and lock geophysical instruments within BR Landing Nipples, a different nipple profile type from the BF nipples served by the ROTFSB and ROTFWB. The ROTRZB is built around a ROTZ-1/2 Lock Mandrel Sub-Assembly, which engages the BR nipple's specific profile geometry. Like the ROTFWB, the ROTC-1 Running Tool used with the ROTRZB must be fitted with a Thread Protector during deployment.

The ROTRZB rounds out Rebco's trio of BF/BR-type nipple instrument hangers, ensuring that operators with completions containing BR nipples, in addition to or instead of BF nipples, have a matched instrument hanger available. All three of the ROTFSB, ROTFWB, and ROTRZB use the same Hanger Sub components and the same instrument box thread connection options, simplifying inventory management when multiple hanger types are required on the same job.

Available in nominal sizes 2⅜" through 4½" in both Amerada and Sucker Rod connections. Non-standard sizes and specialty materials are available upon request.

How to Order: Specify nominal size, seal bore size, and box thread connection (Amerada ¾"–16 or Sucker Rod 15/16"–10). Confirm the BR nipple profile is present in the completion string before selecting ROTRZB over ROTFSB or ROTFWB.
