Performance and Reliability for the Next Frontier in Fuel Technology

For 75 years, Swagelok has improved the operations of many critical applications across industries such as biochemical or petrochemical. Now we are prepared to support alternative fuels in more areas than ever before.

Are you in the business of maintaining natural gas (CNG / LNG) powered heavy or light duty vehicles or constructing alternative fuel filling stations? Or perhaps you are looking for solutions for managing a fleet of hydrogen vehicles, storage tanks, or dispensing station? Are you retrofitting or converting your fuel supply to natural gas? Our team of engineers and technicians are trained and certified to assemble hoses, priority panels, dispensing systems and fuel line assemblies. In addition to our standard high performance product line, we offer engineered-to-order (ETOP) products for specialized applications.

Watch this 5 minute video to see how Swagelok Indiana collaborated with Green Alternative Systems, a fleet-conversion company, to accelerate production time and produce significant labor cost savings.


Swagelok products meet strict manufacturing quality requirements to ensure that products perform optimally and consistently – without failure. Several of our products also meet or exceed compliance and standard measures including AGA, CGA, CSA, ECE, ISO, NGV, and PED.
