O3 Coupling and Adapter
The O3 completion consists of a tubing hanger coupling, coupling nut, tubing head adapter and the T-2W wrap-around hanger. The O3 completion provides a simple tubing suspension system, specifically designed for reciprocation of the tubing string to displace fluids or to set a downhole packer. The primary difference between the O2 and the O3 is that the O3 offers:
- a metal-to-metal neck seal for superior sealing, and
- a coupling nut for simplified make-up of the adapter and tree.
Features –
- Seal between the coupling and adapter is accomplished using a metal taper seal design
- Includes a back pressure valve preparation (Type H standard; others available upon request)
- Uses a coupling nut with coarse ACME OD threads for a safe and easy make-up
- No rotation of the tree required
- Retains coupling to ensure metal seal engagement
- Available with standard API tubing threads or premium tubing threads per customer request
