Since its founding in 1947, Swagelok has built its reputation on the quality of our fittings, and because of the trust we have built with customers the name Swagelok has become synonymous with fittings that perform.

Our fittings continue to deliver value to you by helping to provide a safer work environment, reducing your operating costs and minimizing unplanned system downtime.

Swagelok fittings are relied on by companies, big and small, to work their best every time. When you choose Swagelok fittings you can rest assured that they exceed the strictest of quality requirements.

We can provide a single fitting or a two-piece solution to solve a simple problem. Or we can design and create sub-assemblies or skids, such as sample panels, seal support systems, chemical injection or lube oil skids, even ultra-high-purity gas sticks, boxes, purifier panels and more.

Just like any other component, there is a way to maximize its operational effectiveness by installing it properly. We offer expert-led certified tube fitting installation and safety training for your team to ensure your work environment is safe, proving peak efficiency and eliminating unplanned downtime.

And if you have fitting and other compressed air or gas leaks we have a team of experts, including field engineers, who can pinpoint the issue, prioritize the improvements needed and prove your case to gain approval. Oftentimes, this can lead to hundreds of thousands of dollars in savings, and a significant increase in efficiencies and safety, while eliminating threats of unplanned downtime.

It's important to note that all Swagelok products are backed by our Limited Lifetime Warranty, and that interchanging or intermixing other companies’ components voids the warranty.

Please visit Cole Parmer before you select materials to ensure your fluid system is chemically and materially compatible.
