Quick connect couplings
for supplying and fueling of high pressure hydrogen
HHV CUPLA

HHV CUPLA is active in hydrogen stations (stationary or mobile) all over Japan.
As the use of HHV CUPLA expands to other industrial fields, we keep working to enhance safety and to reduce weight of our products to meet the needs of the market.

Fueling hydrogen to MIRAI, Toyota Motor Corporation's fuel cell electric vehicle

Column

Etymology of the name
"HHV CUPLA"

It was developed with the following initials, and is representative of its developmental purpose of filling next-generation fuel cell electric vehicles with high pressure hydrogen.

Features of receptacle

  • It is widely adopted across the industry as a fueling port for supplying high-pressure hydrogen gas to fuel cell electric vehicles (FCEVs).
  • Unique internal structure prevents the backflow of hydrogen gas from the vehicle side and prevents foreign objects from entering.
  • Sealing technology developed over many years ensures stable sealing, even in ultra-high-pressure environments.
