Gas distribution systems operate to deliver gases from a high-pressure source to the facility at the pressure and flow rate required for each application. Usually built around one or a series of pressure control steps, gas distribution systems can have four typical subsystems: source inlet connection, primary gas pressure control, point of use and automatic changeover.
The Swagelok gas distribution program is designed to help you:
- Reduce costs by preventing leaks and unscheduled maintenance
- Increase uptime and improve process accuracy and repeatability
- Ensure the safety and well-being of system operators and others
- Focus your time and resources where they are needed most

With more than 75 years of experience in fluid systems and a global network of pressure control consultants, Swagelok offers a dual solution: pressure control consulting services and gas distribution systems that ensure facilities operate safely and efficiently.
Our consultants, in collaboration with your team, deliver:
- A fully designed system, assembled and tested prior to installation
- Built with minimal threaded connections to prevent leaks
- Clearly labeled for safety and functionality
- Easy to understand and operate
- Easy to troubleshoot and routinely maintain
Our gas distribution systems are backed by Swagelok's industry-leading warranty. In addition, we provide post-sale support to ensure your system continues to operate accurately.
Swagelok Source Inlet (SSI)
- Highly configurable options to purge or vent gases when changing bottles, always ensuring operator safety
- Available option to vent individual lines to maximize uptime
The source inlet connects the high-pressure gas source and the distribution system. It is important that the inlet is built with appropriate cylinder connections, hoses, tubing, filters and venting, flushing and relief functions to ensure that gas can be safely fed to the primary gas pressure control or automatic changeover. For a single gas cylinder, the assembly may be as simple as a hose and connector. Multiple cylinders may require a manifold with many hoses and valves.
Swagelok Gas Panel (SGP)
- The modular panel is easy to maintain because each component can be removed via a Swagelok connection, so the panel never needs to be removed.
- Options can be implemented around the regulator and valves for color coding if needed for your location.
As the primary gas pressure control, the SGP completes the initial pressure drop of the source gas and ensures it is delivered to the next stage of the system at the proper flow rate. Pressure reduction is achieved in one stage with a single pressure regulator or in two stages through a dual pressure regulator arrangement.
Swagelok Changeover (SCO)
- Optional line control available if your system includes a downstream point of use controller, eliminating the additional cost of a controller at the SCO
- Flexibility to set switching pressure to your specification
The automatic changeover system switches seamlessly from one gas source to another to ensure an uninterrupted supply. This is achieved through staggered set points of two pressure regulators, allowing the system to continue operating while the primary gas source is changed. Our switching station allows for customized switching set points to reduce wasted gas in cylinders.
Swagelok Point of Use (SPU)
- Ensures standardization and consistent operation at the point of use
- Can be set up for both top-down and bottom-up flow to meet your set-up needs
- Compact design and numerous mounting options
The point-of-use system provides the critical final stage of pressure control before gas is used. These are often the least complex of the four main systems, usually involving a pressure regulator, pressure gauge and shut-off valve. Usage point systems offer operators and technicians a convenient and accurate method of adjusting pressure to suit their test bench or equipment needs.

At a leading chemical company, Swagelok identified ways to standardize the design of gas panels. They discovered that flushing and venting components had been added over the years, resulting in unnecessary complexity. Removing critical relief valves via tapered, bolted connections during maintenance required significant labor time. In addition, the customer's use of different gas panels from multiple suppliers made it difficult to plan ahead for replacement. Through the Gas Distribution Program, this customer achieved:
- Improved system and site security
- $52,000 saved on panel replacement every five years
- 75% reduction in gas panel maintenance time
- Standardization of panels that freed up time for more important tasks
- Reduced carbon footprint by stopping leaks and other changes
