Performance and Reliability for the Next Frontier in Fuel Technology

The need for sustainability is driving innovation across the transportation market. Alternative fuel technologies are helping buses, trucks, and other vehicles operate more cleanly and efficiently than ever before. With these advances comes persistent challenges, however. Building fluid systems for applications involving the storage, transfer, and use of pressurized, potentially volatile, small-molecule fluids requires the use of components with advanced performance capabilities. It also requires a strong understanding of materials science, fluid system design best practices, and global alternative fuel industry certifications, standards, and approval processes.

  • Swagelok actively supports companies developing alternative fuel technologies for the transportation industry by providing the fluid system expertise and deep understanding of application requirements they need to compete effectively in a performance-driven, safety-focused market
  • We provide a variety of certified fluid system components and custom assemblies with the tolerances and material compositions to provide leak-tight performance in hydrogen fuel cell, compressed natural gas (CNG), and liquefied natural gas (LNG) vehicles and refueling infrastructure
  • We also consult with customers to help them design or improve upon on-vehicle fuel systems and fueling stations

If you are working toward building a cleaner environment through cleaner mobility solutions, work with the company that transportation companies worldwide trust when their fluid systems must not fail—Swagelok.

Services for the Transportation Industry

Strained workforces, a lack of skilled technicians, and supply chain complexities are just some of the challenges that can make the development of fluid system applications difficult. Swagelok can provide the support you need to overcome design challenges, select components, and troubleshoot issues while developing low-emission fuel storage, transportation, and delivery systems. Come to us for custom subsystems and assemblies built to your exact specifications, ready to be installed. Or, let our experienced fluid system professionals help get your team members get up to speed on fluid system best practices, trends and technology, or installation and safety.

Design and Assembly Services

Have our fluid system professionals build you Swagelok® Custom Solutions that can range from a few components or complete fluid systems, including gas fill panels or assemblies that integrate into dispensers, compressors, and fuel lines. We produce standardized, scalable designs complete with testing, inspection, and packaging, as well as services such as CNC tube bending or preswaging of tubing and fittings.

Field Engineering

Our experienced field engineers are stationed around the world and can help you identify and solve application challenges, troubleshoot problems, and recommend materials based on factors that contribute to corrosion, hydrogen embrittlement, and chemical compatibility issues.

Fluid System Training

A well-trained team can help ensure that your approach is consistent and that your standards are upheld on every installation. Swagelok offers training on topics such as materials science, tube bending, hose routing, orbital welding, and product selection, installation, and inspection, helping you ensure your team members can effectively assemble and operate critical gas systems.

Onsite Services

Swagelok field engineers can visit your production facilities to help you attain the performance you need from fluid systems on light- or heavy-duty vehicles, at mobile or stationary fueling stations, or within the facility. In the process, we can help you minimize costs and fluid system downtime while helping you avoid potential safety hazards and environmental risks.

How We Support The Transportation Industry

Improving Safety

Safety is a high priority in any application involving the handling and transportation of highly volatile fluids. It is especially important when the future of alternative fuel vehicle adoption depends on widespread perceptions that the technology is safe to use. We can help you build safety into your fluid system-related practices, from component installation through routine maintenance. We provide:

  • High-quality Swagelok components and assemblies engineered and tested to keep you safe to operate and maintain throughout their lifecycles, as well as leak-tight fluid system assemblies designed according to best practices for operator safety
  • A comprehensive program of fluid system training programs designed to help new and experienced team members and contractors work more safely by improving their fluid system design, installation, inspection, operation, and maintenance capabilities
  • Evaluation and advisory services that help you address risk factors throughout your fluid systems such as fluid leaks caused by the improper component installation or product selection, inefficient system designs, or selection of materials unsuited for alternative fuel applications

Enabling Performance

Designing hydrogen and CNG/LNG mobility solutions is uniquely challenging. Hydrogen embrittles and degrades many metals, and its small molecule size can lead to leaks if seals are not tight enough. High pressures, rapidly changing temperatures, and persistent vibration all pose challenges to alternative fuel vehicle fuel systems and supporting infrastructure. Our engineers worldwide can help you find the advanced fluid system performance you need by recommending or constructing fluid system components and assemblies configured to suit your requirements.

  • Our standardized, configurable fluid system assemblies are thoroughly tested, inspected, packaged, warrantied, and easy to order with single part numbers. Allow your team members to focus their attention on more pressing tasks than design and assembling systems by choosing fluid system assemblies built according to best practices through our Custom Solutions program.
  • Our experienced product design engineers have the technical knowledge, advanced software, and manufacturing expertise to customize fluid system products to meet demanding specifications. They can help with applications such as fuel line integration, CNG priority panels, dispensing systems, heavy-duty refueling boxes, and much more.
