Hunting’s Subsea Technologies Division is the world-wide leader in the subsea oil and gas industry for hydraulic coupling technology, performance and installed base. We have supplied over 1 million hydraulic couplings to subsea projects, and we offer more than 3,500 different male and female coupling designs for subsea applications.
The packaging versatility and high reliability of our hydraulic coupling product line provide significant benefits to equipment suppliers and operators alike.
Each hydraulic coupling series features unique design characteristics, allowing our products to meet the requirements of a broad range of applications. These applications vary from low-pressure, shallow water connections to the most critical component of HPHT and ultra-deepwater systems.
Hunting’s hydraulic couplings have been installed in subsea applications including, but not limited to:
• Subsea Trees
• Tubing Hanger Penetrators
• Production Control Systems
• Subsea Control Modules
• Drilling Control Systems
• ROV Hydraulic Flying Leads
• Chemical Injection Systems
• Installation/Workover Control Systems
• ROV Hot Stabs
• Metal Seal Hydraulic Couplings
The RS-Series compact hydraulic coupling line is designed for tubing hanger penetrator and subsea ROV flying-lead connector applications where reduced size, weight, separating loads and travel distances are critical requirements.
The UO-Series hydraulic coupling line answers market demands for a smaller, lighter and higher flow coupler for extreme working pressures in ultra deepwater.
The TO-Series hydraulic coupling line was developed for deepwater applications, requiring the highest possible reliability, under the most severe working pressures.
The RO-Series hydraulic coupling line is for hot stab diver or ROV make-up applications, used for subsea trees, control pods, manifolds and chemical injection.
The TM-Series hydraulic coupling line is for both surface and subsea applications where manually threaded make-up connections are desired.
The AS-Series hydraulic coupling line is our highest pressure-rated elastomer seal coupling, designed for working pressures of up to 17,500 psi.
The HCC-Series hydraulic coupling line is for general economical purposes and low-pressure applications, generally utilized for hydraulic umbilical junction plates and is not recommended for subsea applications.
The HO-Series hydraulic coupling line is designed for various intermediate pressure applications and primarily utilized for hydraulic umbilical junction plate tie-ins, power units and shallow water diver/ROV stab applications.
The AO-Series hydraulic coupling line is designed for ease of seal replacement and adaptable to a wide range of applications, including flying lead connectors, umbilical terminations and subsea junction plate assemblies.
General design requirements should be considered “best practice” for most applications. These design requirements are intended to serve as basic guidelines for performance optimization of pin and box type hydraulic couplings and apply to a broad spectrum of applications.
