Chemical and Refinery Applications

Process and analytical instrumentation are the core of any chemical and refining plant. They help ensure product quality and high yield rates with maximum production throughout your operation. Swagelok is an industry expert when it comes to analytical systems that provide leak-tight, working solutions for complex and corrosive fluid applications. Our company has extensive experience in manufacturing analytical systems, fluid system assemblies as well as a full range of liquid and gas grab sample panels and sample cylinders.

Products for the Chemical & Refinery Industry

Swagelok® fluid system components and assemblies for chemical processing can be trusted to help you minimize downtime, maximize production efficiency, and meet strict standards for emissions control. Our fluid system products are backed by the Swagelok Limited Lifetime Warranty. 

Swagelok® Tube Fittings and Adapters

Swagelok tube fittings deliver a leak-tight, gas-tight seal that is resistant to vibration fatigue, even in harsh environments or stressful applications. They withstand high pressures and temperature extremes and are easy to install, disassemble, and reassemble in a variety of situations.


From the far reaches of space to the bottom of the ocean and everywhere in between, trust leak-tight, long-lasting Swagelok valves in your critical applications. Known for durability derived from carefully controlled manufacturing practices, our valves perform reliably even after years of use in demanding applications.

Swagelok® Regulators

Reliable pressure control is essential to the safe operation of your fluid systems. At Swagelok, we have the right combination of regulators to fit practically any situation, and our advisors can help you find a configuration that will maintain pressure and minimize droop over a wide range of pressures and flows.

Swagelok® Tubing and Tube Accessories

Find reliable tubing options with the material properties needed for your application. Make sure your system is built to last with tubing accessories that help you cut, bend, deburr, and support tubing so it provides leak-tight performance.

Swagelok® Hoses and Flexible Tubing

Swagelok hoses and flexible tubing are trusted to perform in industrial facilities worldwide, transporting liquids and gases that are crucial to operations. Choose from a variety of core materials, reinforcement styles, end connections, or insulation options to find products that suit the pressures and temperatures of your applications.

Swagelok® Sample Cylinders

Swagelok offers a wide selection of sample cylinders that are compliant with various transportation industry standards related to chemical transfer. These durable, pressure-rated metal cylinders also prevent samples from escaping during grab sample system operation and are easy to clean.

Swagelok® Filters

Contaminants can lead to off-spec products and other problems downstream, but the right fluid system filters can help you avoid these issues. If your operations could benefit from the removal of liquid or particulate contaminants from your fluid systems, Swagelok filters can help you achieve reliable system function and repeatable results.

Swagelok® Smart Products

Swagelok's PTX series transducers and VCM digital control module smart products work together to capture and report the critical flow, temperature, and pressure of process samples destined for process analyzers.

Swagelok® Miniature Modular Systems

Increase efficiency and decrease footprint with Swagelok analytical miniature modular systems. These modular platform components and systems reduce design and assembly time and yield reliable results.





Services for the Chemical & Refinery Industry

We provide a variety of services to chemical companies that help them minimize downtime, improve process efficiency, avoid leaks, and trust their analytical instrumentation. Look to Swagelok specialists for help building custom fluid system assemblies, consulting on system designs, addressing fluid system issues, and delivering training to your team members.

Onsite Services

Faulty fluid systems consume financial resources and the time and attention of technicians needed elsewhere. Swagelok shares advice for engineering a more efficient operation, from improved maintenance practices to making systems smarter.

Fabrication and Assembly Services

If you are experiencing issues with the performance of existing fluid systems or simply lack the resources to design and build reliable subsystems, our local specialists can engineer and fabricate kits, assemblies, and subsystems optimized for your operations.

Field Engineering

Swagelok-trained professionals can help guide component, material selection and system design from afar or visit your onshore or offshore facilities to evaluate your fluid systems, providing detailed recommendations on installation practices and system enhancements.

Fluid System Training

We can provide the knowledge needed to keep your fluid systems operating safely and effectively with training covering fluid system design, installation, operation and maintenance, materials scienceweldingfluid sampling, and more.



Design & Assembly

Take Fluid System Design and Assembly Off Your To-Do List

Our assemblies are locally built with Swagelok's high-quality fluid system components. We can also incorporate third-party products, including wiring, automation, transmitters, relays, motors, and more. We produce professional-grade, reliable solutions, complete with testing, inspection, and packaging, all backed by the Swagelok Limited Lifetime Warranty.


Swagelok Custom Solutions are fabricated assemblies that range from systems with just a few components to full panels, enclosures, and beyond. We can follow your design or develop a new one with our custom engineering services.
