Chemical & Refining

Comprehensive Support for an Evolving Industry

With process and analytical instrumentation from Swagelok Minnesota | North Dakota | Appleton, you get the knowledge you need to drive the solutions that optimize your process. 

From maintaining accurate pressure, temperature, flow and analytical measurements to improving uptime of rotating equipment and emissions monitoring systems, the pressure to improve performance doesn’t stop. For that, you don’t just need high-quality parts—you need partnerships. That’s what you get with us.

Studies on reliability-related mechanical downtime and slowdowns in chemical plants have found that efficiency losses or product loss due to fluid system fouling, plugging, freezing, corrosion, and cracking is common. Improving your fluid systems through energy audits, sampling system optimization, and mechanical efficiency programs can yield:
  • Reduced labor required for maintenance
  • Improved process efficiency for high performance rotating equipment, heating systems, and reactors
  • Optimized performance of utilities
  • Improved energy intensity metrics


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

Analytical Instrumentation

We offer fully engineered assemblies such as gas distribution systems, mechanical seal support systems, and analytical subsystems to improve reliability and simplify use and maintenance.


Avoid particulate contaminants leading to off-spec products, inaccurate analyzer readings, or other problems downstream with filters designed to preserve the integrity of your processes.


Whether you need fittings for corrosive environments, extreme temperatures, or high pressure, we have a variety of reliable, leak-tight products for use in chemical processing.

Hoses and Flexible Tubing

Choose from millions of variations of metal core, PTFE/PFA core, rubber core, and thermoplastic core hose and flexible tubing options to find products that meet the performance criteria of your applications.

Measurement Devices

Maintain optimal fluid conditions with measurement devices such as pressure gauges, pressure transducers, flow sensors, flowmeters, thermometers, and additional measurement devices that are easy to use and read.


Maintain precise pressure control throughout your fluid systems with pressure-reducing (spring-loaded or dome-loaded), back-pressure (spring-loaded and dome-loaded), and specialty regulators capable of handling a wide range of pressures and flows.

Tubing and Tube Accessories

Find tubing with the material composition and performance characteristics needed for your application, as well as accessories used to cut and deburr, bend, swage, and support tubing.


Our dependable valves perform reliably even after years of use in demanding applications. Find the ball valves, check valves, needle valves, relief valves, manifolds, and more needed to appropriately control flow in your small-bore fluid systems.

Welding System

Weld consistently and efficiently with the Swagelok orbital welding system, which provides cost-effective, reliable orbital gas tungsten arc welds (GTAW) for both tubing and pipe.


We provide a variety of services that help them minimize downtime, improve process efficiency, avoid leaks, and trust their analytical instrumentation. Swagelok Minnesota | North Dakota | Appleton can build custom fluid system assemblies, consult on system designs, address fluid system issues, and delive training to your team members.
