Swagelok developed the original two-ferrule tube fitting in 1947, and with over 200 active patents worldwide, we continue to improve our proprietary design for use in thousands of applications.
BETTER BY DESIGN
The Swagelok® tube fitting's extraordinary performance comes from a combination of design features.
The Swagelok patented geometry of the back ferrule provides a hinging colleting action that enables the Swagelok® tube fitting to perform extraordinarily well in three key factors:
| Tube Grip
The unique hinging-colleting action provides more direct tube contact and gripping support.
The burnishing/polishing action creates concentrated zones of contact for a gas-tight seal.
The colleting region more effectively isolates any stress riser at the tube grip from system vibration.
The controlled phased sequential pull-up and contoured geometry, along with the SAT12 patented surface hardening process of the back-ferrule, enables the tube fitting components to work together in systematic harmony during assembly.Back To Top
A MATERIAL DIFFERENCE
The Swagelok® tube fitting is made of high quality raw materials for superior performance.
1. Swagelok's Stainless Steel – ASTM requires 16-18% chromium and 10-14% nickel. Swagelok has maintained chromium content in its fittings at a minimum of 17% and nickel at a minimum of 12% for many years.
2. Quality Barstock – We place multiple controls on procurement of 316 stainless steel from our approved mills, from its elevated alloy chemistry to the inspection steps used to validate it to ensure uniform manufacturability when making our tube fittings.
3. Chloride Stress Corrosion Cracking (CSCC) in 316 Stainless Steel – CSCC occurs where chloride concentrations and stress levels are present. We have performed extensive CSCC testing on Swagelok fittings with exceptional results: Alloy 316 stainless steel nuts tested (Swagelok and eight other brands): None of the Swagelok nuts cracked or leaked. 39% of the other nuts cracked (at least one from each brand) and 2.7% leaked
4. Alloys and Corrosion - Swagelok offers a wide range of alloys and works closely with customers to solve their needs for fittings with enhanced chemical and corrosion resistance.
5. Engineered Combinations - Swagelok can engineer a cost-efficient and corrosion-resistant solution for installations exposed to seawater.Back To Top
EXCELLENCE IN MANUFACTURING
