Worry-Free Code Compliance

Swagelok has been a supplier of products to the nuclear industry for decades and has an agreement with NuSource LLC, an accredited ASME N Certificate Holder, to allow NuSource to offer code-compliant and safety-related valves that are manufactured by Swagelok.

Complete Tracability

All fittings are marked with the Swagelok name, material type, and trace identifier. All other products are identified with standard markings, either directly on the product or on the attached tag.

High-quality Commercial Grade Components

Most Swagelok products can be used in commercial-grade applications within the nuclear industry. Swagelok has maintained its ASME certification since 1981, and our standard cleaning process (SC-10) meets non-nuclear commercial grade general industrial requirements.
