Swagelok offers a wide range of fluid system components for use in many types of hydrogenrelated applications including the infrastructure that produces, transports, compresses, stores, and fills cylinders with hydrogenand for on-vehicle use.Swagelok products, as listed in this document, are compatible with both on-vehicle and infrastructure hydrogen applications.Hydrogen-compatible products have had the materials of construction reviewed for appropriateness for use with hydrogen.Some metals are susceptible to hydrogen embrittlement, specifically hardened Belleville springs and stems. These have beenreplaced with less susceptible materials for compatibility with hydrogen service. Some elastomers are also more susceptible tohydrogen degradation and have also been replaced with more resilient materials. Products not listed in this document may notbe suitable for hydrogen applications.On-Vehicle ApplicationsOn-vehicle applications include light-duty (car and van), heavy-duty (bus and truck), rail, ship, and aerospace. Componentsused in light-duty cars and vans and heavy-duty trucks and buses may require EC-79 certification for use at working pressuresabove 30 bar (435 psig). Specific testing is required to achieve this certification, including corrosion resistance, endurance,hydraulic pressure cycle testing, and external leakage testing. Products with this certification will be specially marked toreflect the approval. Products certified for EC-79 are based on the nominal pressure of either H35 or H70 pressure classes. Allproducts are tested and certified to the MAWP for the pressure class.Fuel Cell Electric VehiclesHydrogen-compatible Products AvailableRefer to Hydrogen-Compatible Products for ApplicationsUp to 1 378 bar (20 000 psig) on page 4 for additionalinformation.

Swagelok Hydrogen-Compatible Products3EC-79 Certified Products:EC-79 certification for on vehicle applications come in two pressure classes: H35 Pressure class above 30 bar (435 psig) and Up to 350 bar (5 076 psig) see page 6 and 7 for additionalinformation. H70 Pressure class above 30 bar (435 psig) and Up to 700 bar (10 159 psig) see page 8 and 9 for additionalinformationInfrastructure ApplicationsInfrastructure applications include the dispensers, storage cylinders, compressors, separators, and pressure control devicesthat make up the station, as well as the hydrogen tube trailers that bring the hydrogen to the stations. Components in theselocations must be hydrogen-compatible but may not require specific certifications. In addition to standard Swagelok tubefittings, a range of FK series medium-pressure fittings, cone and thread fittings, hoses, valves, and pressure gauges that arehydrogen-compatible are available.Note: F or these applications, regional standards and specifications may vary.
