Our founder invented the original two-ferrule tube fitting in 1947. Since then, Swagelok has added 6,000+ offerings—innovating at every step. Today, with over 200 active patents worldwide, we continue to lead.

Whether you need fittings to withstand corrosive environments, extreme temperatures, or high pressure, you’ll be well-connected with Swagelok.

For example, the Swagelok tube fitting's patented back ferrule geometry and patented SAT 12 case hardening process provides an advantage in a range of applications.

Tip: Many pros assemble tube fittings by feel, and that usually means under-tightened connections. Learn about our Swagelok Tube Fitting Safety Seminar.
