Latest generation premium semi-flush fit for critical applications.

VAM® SLIJ-3 is the latest generation of VAM® semi-flush premium connections, introducing higher torque and compression capacity for an overall superior performance in ultra-deep offshore environments. Its optimized design improves make-up and brings higher value in HP/HT operations. VAM® SLIJ-3’s robustness was tested with the most recent and rigorous test protocols thus guaranteeing reliability in critical operations.

High performance
Maximum performance envelope and optimized design with improved tension and compression capacity.
Slim Design
Best compromise between design efficiency and tight clearance requirements.
Optimizes well design
First-class choice for the most stringent casing applications.
Performance, Application & Product Range


  • Extensively tested to the highest industry requirements: API RP 5C5:2017 CAL-IV across the entire Product Line
