HC.AIR connector for hydrogen and fuel cell systems

  • HC.AIR connectors are charge air connectors that comply with VDA standard spigots.
  • HC.AIR connectors have been in serial production since 2018 as a further development of the HC+.
  • Due to their robustness, low assembly forces and high quality, they are increasingly replacing conventional clamped connections within the automotive industry.
  • HC.AIR connectors are manufactured as one stainless steel part, which provides stability and excellent corrosion properties.
  • The manufacturing process is fully automated and monitored.

      HENN Connector Group

      As a top global player, we develop highly innovative connection systems. With our couplings for fluids, air and gases made of metal and plastic – manufactured using deep drawing, injection molding, turning/milling or additive manufacturing processes – we hold over 200 patents in 16 different countries.

      In the course of the EU-funded project HyTechonomy, we evaluated our couplings for hydrogen applications inside and outside of automotive applications and can now offer proven products for any circulation system (air, water and hydrogen).

      What drives us? Our mission to make great things happen through connections. With progressive technology, outstanding quality, excellent customer service and one common goal:

      Strong connections. Big impact.
