The Making of a Swagelok Tube Fitting, Part 3

Swagelok warehouse associates factory associates

After Swagelok welds your component, assembly begins. Swagelok tube fittings are one of the products we call Assemble to Order (ATO) products. Swagelok also carries products designed especially for your unique needs – Make to Order (MTO) and Engineer to Order Products (ETOP). Trained associates assemble every Swagelok tube fitting.


Swagelok then performs continuous, rigorous quality testing on thousands of samples to make our reliable components. Swagelok also offers the most comprehensive book of tube fitting Product Test Reports (PTRs) in the industry for validation. For instance, one of Swagelok’s tests is Chloride Stress Corrosion Cracking (CSCC) in 316 Stainless Steel. CSCC occurs where chloride concentrations and stress levels are present. Swagelok fittings have exceptional results in extensive CSCC testing. When experts tested Swagelok’s Alloy 316 stainless steel nuts against eight other brands, none of the Swagelok nuts cracked or leaked.
