Clean Energy

Quality components are fundamental for maintaining your safety, performance, and credibility across the clean energy market. But quality components alone will not help you achieve the consistency necessary for long-term success. To sustain your success, you need a supplier that not only provides high-performance components but also offers tailored and comprehensive support that empowers you to improve your system and increase your impact on the industry. refueling-hydrogen-vehicle-content

Alternative fuel technologies are helping buses, trucks, and other vehicles operate more cleanly and efficiently than ever before. With these advances come other 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 Minnesota | North Dakota | Appleton actively supports companies developing alternative fuel technologies for the clean energy industry
  • We provide fluid system expertise and a deep understanding of application requirements that will help you 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 refueling stations
For more than 75 years, the Swagelok offering has improved the operations of many critical applications across the clean energy sector; we have served the industry in thousands of CNG, infrastructure projects, passenger, and commercial vehicles and select LNG and hydrogen applications around the world. Work with a company that transportation companies around the world trust when their fluid systems cannot fail—Swagelok.

Continuing Innovation

  • High-horsepower vehicles


All our standard products and custom components are backed by the Swagelok Limited Lifetime Warranty. Hydrogen fuel cell, natural gas, or other synthetic fuels (ethanol, methanol, biodiesel, etc.) on-vehicle fluid systems and the infrastructure used to fuel them require high-integrity system components that effectively contain high-pressure, small-molecule gases. We provide OEMs with high-performance fluid system products specifically engineered for the toughest challenges in the specialty fuels markets. Our components are designed to deliver the seal tightness, grip strength, thermal performance, corrosion resistance, ductility, and ease of assembly needed to make alternative-fuel vehicles and infrastructure viable. 


Find and install all-welded inline or tee-type filters that remove system particulate contaminants from your alternative fuel systems.


We offer a wide variety of fittings for alternative fuel system applications, including Swagelok® FK series fittings, assembly-by-torque (AbT) fittings that are quick and easy to install, and Swagelok® tube fittings that deliver gas-tight seals resistant to vibration fatigue.

points in refueling stations.

Engineering Services

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. We can provide the support you need to overcome design challenges, select components, and troubleshoot issues while developing low- or zero-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, compressors, and fuel lines. We produce standardized, scalable designs complete with testing, inspection, and packaging, as well as CNC tube bending and 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 ensure your team can effectively assemble and operate critical gas systems.
