DEENPU Tubing Hanger Spool and Tubing Hanger Coupling
API 6A Wellhead
Home › Wellhead Equipment & Christmas Trees › Tubing Hanger Spool & Coupling
Product Overview
The DEENPU tubing hanger spool and tubing hanger coupling provide a means of suspending the tubing string in wells using wrap-around tubing hangers. The coupling screws the union nut of the tubing hanger down without the need to turn the Christmas tree — a major advantage when the tree is fitted with flowlines or actuated valves that must not be rotated.
The coupling is threaded to accept a back-pressure valve, and is machined from high-strength alloy steel with full load-rated threads for the weight of the tubing string plus annulus pressure loading.
Key Features
- Installs tubing hanger without rotating the Christmas tree
- Threaded for back-pressure valve installation
- Compatible with wrap-around and slip-type hangers
- Full tubing load rating, heat treated alloy steel
- Sizes and threads per API 6A tubing program

- Temporary suspension during completion transitions
Frequently Asked Questions
Q: When is a tubing hanger coupling needed instead of a standard tubing head?
A: When the well is completed with a wrap-around hanger, or when the Christmas tree cannot be rotated during hanger installation — the coupling lets you set the hanger from above.
Q: Can it hold a back-pressure valve?
A: Yes, the coupling is threaded to accept a standard back-pressure valve for annulus pressure control.
