The Power to Connect, Convey, Control, and Customize

Swagelok products support a broad range of power industry applicationsCompanies that generate, store, convert, or convey power need fluid systems that provide leak-tight performance. From nuclear, hydroelectric, thermal, gas- and coal-fired plants to combined cycle and cogeneration facilities, Swagelok stands behind the power industry with the products, services, and training to perform under pressure. These pressures can come in many forms including:

  • Costly problems like vibration, leakage, thermal shock, and improper installation that may also lead to safety concerns
  • Evolving environmental regulations that demand engineering and fabrication support to reduce greenhouse gas (GHG) emissions
  • Changing safety and industry standards such as ASME Section III for the nuclear sector that challenge companies to keep pace

High pressures and temperatures, superheated steam, hazardous chemicals—all require fluid system solutions that are suited for harsh, high-stress environments. Swagelok® products have been proven in critical power industry applications for over 75 years. Across the world, energy producers, storers, and distributors trust our design and manufacturing expertise to help them keep the power on.

Products for the Power Industry

Our fluid system products are supported worldwide by 200-plus authorized Swagelok sales and service centers and are backed by the Swagelok Limited Lifetime Warranty. From commonly used products to custom components and assemblies, everything we design, manufacture, and build is to ensure the highest level of application, process, and instrumentation integrity.

This page highlights only a few of the products available for fuel delivery, gas distribution, steam sampling, water sampling, CEMS, lube oil, and other critical power plant systems. We also provide solutions for assets like boilers, generators, industrial gas turbines, and an array of rotary equipment. Many products are designed to ASME nuclear codes and standards.



Leak-tight fittings are fundamental to a worry-free operation. The Swagelok name is synonymous with safety and dependability. Find tube fittings, transmitter calibration fittings, PFA fittings, and more for standard applications or where reactive and corrosive chemicals are a concern. Many alloys and configurations are available.



The true cost of a valve is what goes into maintaining or replacing it over time. Swagelok is a proven option for lasting performance. Turn to us for process and instrumentation ball valves (40, 60, GB series), check valves, needle and metering valves, relief valves, plug valves, bleed and purge valves, and bellows-sealed valves as well as manifolds and stream selector systems for process analyzer applications.

Small bore tubing system

Small-Bore Tubing

We have the small-bore tubing to form the backbone of your fluid delivery system. Compared to conventional piping, small-bore tubing (up to 2 in. [50 mm] O.D.) reduces the number of connections and thus potential leak points for greater system integrity. No welding, cutting, or threading of pipe means less required labor, lower installed costs, and no fire watch needed. Using bends instead of elbows helps improve fluid flow.

Hose and Flexible Tubing

Hoses and Flexible Tubing

Choose from a variety of core materials, reinforcement styles, and end connections to suit virtually any pressure and temperature requirement. Get bulk hose, hose assemblies, and custom hose lengths in sizes 1/8 to 2 in. Also find metal core hose rated to 1000°F and PTFE core hose to 450°F along with PFA and vinyl flexible tubing for even more chemically resistant options for low-pressure applications.



Get precise control with the right pressure regulators. Swagelok pressure-reducing (spring-loaded or dome-loaded), back-pressure (spring-loaded and dome-loaded), and specialty regulators are capable of handling a wide range of pressures and flows to help you safeguard your facility.

Swagelok pressure gauge

Pressure Gauges

We have a variety of gauges designed for all conditions from low pressure to severe service. Multiple-mount configurations also make Swagelok gauges convenient to install. Additional measurement devices include pressure transducersflow sensors, and thermometers.

Swagelok quick connects

Quick Connects

Connect quickly and with confidence using our wide variety of quick connect configurations to reduce spillage and air inclusion in your system. We offer full-flow, instrumentation, miniature, and PTFE-sealed Quick Connects.



Avoid particulate contaminants leading to inaccurate analyzer readings or other problems downstream with particulate filters and coalescing filters that are designed to preserve the integrity of your power plant processes.

welding system

Welding System

Weld precisely and consistently with our orbital welding system, which provides cost-effective, reliable orbital gas tungsten arc welds (GTAW) for both tubing and pipe. Make quality welds with fewer preparations than manual methods. Orbital welding also poses less fire hazards, helping you prevent incidents and injuries.

Power plants need flexible engineering and fabrication support to adapt to changing industry standards and environmental regulations. We provide fluid solutions for both instrumentation and monitoring needs and can help you standardize your operation around common and custom components to reduce costly leaks and emissions.

  • Find tubing, tube fittings, and other products engineered to ASME Nuclear Quality Assurance (NQA-1), Section I, Section II, and Section III requirements. We can assist you when making system changes and at times, avoid a new design review that is not fast or simple.
  • We work with decision-making groups at all levels to clearly communicate project goals and coordinate a plan of action across departments, helping you maximize your internal resources.
  • Get professional assistance for meeting ISO, NFPA, OSHA, EPA, and other industry or region-specific policies. For example, we can provide guidance around U.S. Nuclear Regulatory Commission (NRC) regulations, Japan’s Ministry of Economy, Trade and Industry (METI) standards, or policies set forth by The High Pressure Gas Safety Institute of Japan (KHK). Our specialists worldwide know the most up-to-date compliance information for your region.

Safe fluid system operation in the power industry

Improving Plant Safety

High-vibration, thermocycling applications need leak-tight connections to operate reliably. Other times, corrosive environments demand tubing and tube fittings made from exotic alloy combinations that withstand harsh conditions. Many plants are also now also using advanced materials to generate power under more severe combustion conditions. These are just a few of the reasons why safety is Swagelok’s highest commitment to the industry.

  • Safety is the result of products, people, and approach. We can recommend actions to help improve the safety of your facility that take applications and the human element into account.
  • We can show you how small-bore tubing can drastically reduce the potential for leaks compared to pipe and pipe fittings, which makes your power plant safer and more efficient
  • We will help you avoid the dangers of intermixing or interchanging fluid system products from different manufacturers—a problem that is hard to solve but can be mitigated by working closely with your site contacts
  • We offer onsite training led by experienced instructors that puts safety at the center of all plant operations involving fluid systems as well as air and compressed gas systems.

Simplifying sustainability in the power industry

Simplifying Sustainability

We can support your goals for reducing scope 1, 2, and 3 emissions to meet environmental, social, and governance (ESG) performance standards. There is a lot to consider as the power industry works to minimize GHG emissions. Our specialists can assist you with mounting pressures from regulators, investors, and customers.

  • Field engineering services support your decarbonization goals by identifying leak points in fluid systems, determining where energy is being wasted in your processes, and suggesting options like low-emissions valves or closed-loop grab sampling panels that help reduce fugitive emissions.
  • Swagelok materials scientists and product engineers can help you choose fluid system products and alloys that are optimized for your process. Proper selection also limits the potential for environmental damage due to leakage.
  • When controlling direct emissions, we can help you by recommending analytical instrumentation and system designs for continuous emissions monitoring in flares, stacks, or other areas around power stations.
