Description Vendor

Connects the transfer hose to a liquid-hydrogen receiving interface. A dry-disconnect/cryogenic coupling makes a sealed mechanical connection before flow is permitted. Design details include cryogenic coupling architecture with insulated cold-side path and ambient outer mechanism. Supported applications include liquid-hydrogen truck fuelling, ship bunkering and transfer systems. Configuration: DN32; designed for -253 °C liquid-hydrogen service.

Use Cases

  • Liquid-hydrogen truck fuelling
  • Ship bunkering
  • Transfer systems

Capabilities

  • Configuration: DN32
  • Designed for -253°C liquid-hydrogen service
  • Cryogenic hydrogen transfer capability
  • Dry connection and disconnection operation
Mann Teknik AB Mann Teknik AB (MannTek), a leading Swedish manufacturer of advanced coupling solutions headquartered in Mariestad, Sweden, is an active pioneer in the hydrogen sector with three decades of experience in fuel handling and cryogenics, having developed specialized couplings for hydrogen and other demanding fluid transfer applications. In February 2026, MannTek completed the acquisition of Insplorion AB's hydrogen sensor business for approximately SEK 5.5 million (asset sale), formalized through negotiated definitive agreement terms expected to close in Q1 2026, expanding MannTek's hydrogen technology portfolio beyond its established coupling solutions to include hydrogen sensing capability. Building on its core competency in advanced coupling design developed originally for cryogenic and fuel handling applications, MannTek's coupling solutions serve applications requiring safe, leak-free connection and disconnection of hazardous fluids and gases including hydrogen, positioning the company at the intersection of mechanical fluid transfer hardware and gas sensing technology following the Insplorion acquisition. Led by Co-Founder and CEO Markus Backstrom, MannTek continues expanding its hydrogen sector presence by combining its established coupling technology expertise with newly acquired hydrogen sensor capabilities, positioning the company to offer a broader range of hydrogen safety and fluid handling solutions to the growing hydrogen infrastructure and mobility market.
