New 700 Bar High Pressure Hydraulic Quick Coupling for New Energy Equipment Applications
The renewable energy sector is pushing hydraulic systems to their limits – and we’ve been watching closely. Wind turbine blade tensioning, solar tracking systems, and hydrogen fuel cell infrastructure all demand connections that can handle extreme pressure without compromise. That’s exactly why we developed our new 700 bar (70MPa / 10,000 PSI) ultra high pressure quick coupling.
What makes this coupling different?
Let’s be honest – there are plenty of Quick Couplings on the market. But when you’re working at 700 bar, “good enough” isn’t an option. Our newultra-high pressure quick connector is engineered specifically for new energy equipment applications where reliability isn’t just a feature – it’s a safety requirement.
The numbers speak for themselves: 700 bar working pressure, 10,000 PSI rating, and zero-leak performance under extreme thermal and mechanical stress. Whether you’re connecting hydraulic bolt tensioners for wind turbine maintenance or building out hydrogen refueling stations, this coupling delivers the kind of performance that keeps operations running and technicians safe.
Why we built it
We’ve been manufacturing hydraulic quick couplings since 2010. Over the years, we’ve supplied HL brand couplings to more than 30 countries – the US, UK, Germany, Spain, Italy, Russia, and across Southeast Asia. We’ve seen firsthand how the energy transition is changing what customers need.
Traditional couplings weren’t designed for the new energy sector. Higher pressures, more frequent connect/disconnect cycles, and tighter safety margins. So we went back to the drawing board. The result? A 70MPa Quick Connector that meets ISO standards and interchanges with major brands like Parker, Faster, and Aeroquip – but at a price point that makes sense for growing operations.
Built for the real world
This isn’t a lab experiment. Our ultra high pressure coupling is already being specified for:
- Wind turbine hydraulic bolting systems
- New energy vehicle battery cooling circuits
- Hydrogen fuel cell supply connections
- High-pressure hydraulic test equipment
- Portable hydraulic jacks and rescue tools
Quality you can trust
We’re a factory, not a middleman. That means we control every step – from raw material sourcing to final testing. Our quick couplings conform to ISO 7241-1 Series A & B, ISO 5675, ISO 16028, and Chinese standards. And we back every unit with the kind of quality that’s earned us partnerships with customers in over 30 countries.
The bottom line
If you’re working with ultra-high pressure hydraulic systems in the new energy space, you need connections that won’t let you down. Our new 700 bar coupling gives you the performance of premium European brands at a competitive price – without the long lead times.
