The 350 BAR HFR filling receptacle is a specialized component designed for hydrogen fuel cell systems. It is equipped with a 50-micron filter, a check valve, a dust protection cap, and an SAE J2600 nozzle profile. The receptacle has a maximum flow rate of 370 g/s at a maximum pressure differential of 438 bar. It is compatible with various outlet types, including Pipe OD 3/8, 7/16-20 UNF 2B, Pipe OD 10 mm, and Voss Lock, all featuring Nut Hex 25 mm bracket connections. The product operates at less than 0.5 bar pressure and has a Kv value of 0.69. It ensures safe and efficient hydrogen filling with built-in protection against contaminants and backflow.

Use Cases

  • Typically used in hydrogen and related industrial applications.

Capabilities

  • Enables hydrogen refueling interface compliant with SAE J2600 nozzle geometry
  • Integrates filtration (50 µm) and backflow prevention (check valve)
  • Supports high flow rates up to 370 g/s under defined pressure differential conditions
  • Compatible with multiple outlet connection standards (pipe, UNF, Voss Lock)
  • Provides mechanical integration via Nut Hex 25 mm bracket connection
OMB SALERI S.P.A. SOCIETÀ BENEFIT OMB Saleri SpA, headquartered in Brescia, northern Italy and now organized as a Società Benefit (Benefit Corporation), is considered one of the world's leading specialists in components for hydrogen storage solutions and a leading manufacturing company of valves and components for alternative fuel vehicles, with hydrogen mobility representing the company's main growth perspective after nearly 10 years working with the world's leading fuel cell vehicle manufacturers across cars, trucks, trains, and aerospace applications. OMB Saleri's comprehensive hydrogen product range covers the entire H2 flow path from filling station through high-pressure tanks, pressure regulator, and finally to the fuel cell, spanning products for storage systems (350 bar and 700 bar operating pressures) and fuel cell systems, with the OTV Gen2 On-Tank Valve (multifunctional, anodized aluminum, EC79 certified) and HPR 700/350 bar Pressure Regulator (mechanical double-stage design for fuel cell applications) among its flagship offerings, complemented by the innovative SMA-TPRD thermal relief device reducing complexity and cost. OMB Saleri was selected by Daimler as a supply chain development partner for hydrogen components in next-generation fuel cell electric vehicles, supplied hydrogen tank valves for the first EC79-certified hydrogen-powered train, and uses Siemens Simcenter Amesim software to simulate valve mechanical deformation, flow rate, and magnetic force for rapid new product development, with products approved worldwide and used on forklifts, cars, trucks, buses, trains, and planes, alongside components for gas transportation, industrial applications, and products for liquid hydrogen currently under development.
