Subsea Hydraulic
CAT-D Couplings
Our cutting edge hydraulic couplings support optimized system design while reducing costs and risks associated with welding, inspections, and more.
Why Weld More When You Can Weld Less?
Fully machined to include an adapter and tubing extension, our hydraulic couplings significantly reduce the cost and time associated with welding, inspection, and associated documentation. Metal-to-metal and simultaneous dual sealing poppet technology increase performance while the coupling’s cartridge design eliminates the need for special tooling when replacing poppets and seals.
The Future of Couplings
Significant Cost Savings
- Weldless design simplifies assembly and reduces cost
- Superior performance and lowered cost for multiple applications throughout subsea systems
- CAT design simplifies supply chain
Simplified Fabrication and Assembly
- System can be flushed without seal-containing cartridge
- Coupling available in front and rear loading configurations
Optimized Performance
- Improved flow coefficient supports optimization of system design
- Removable cartridge design enables seal replacement without special tooling
