Features
Two-Ferrule, Mechanical Grip Design
The two ferrules separate sealing and tube gripping functions; each ferrule is optimized for its function. The front ferrule creates a seal against the fitting body and on the tubing outside diameter. As the nut is turned, the back ferrule axially advances the front ferrule and radially applies an effective tube grip
Advanced-Geometry, Hinging-Colleting Back Ferrule Design
 |
| During assembly of the advanced-geometry design (above), the front ferrule is driven into the fitting body and the tubing to create primary seals, while the back ferrule hinges inward to create a strong grip on the tubing. The back ferrule geometry allows for an improved engineering hinging-colleting action that translates axial motion into radial swaging action on the tube, yet operates with a low assembly torque requirement. | This design is standard on all 1/4 to 1/2 in. and 6 to 12 mm Swagelok stainless steel tube fittings to help installers make more consistent, leak-tight tube connections.
In these sizes, a patented case hardening process and patented recessed and contoured geometry provide unique engineering to the Swagelok back ferrule. The hinging-colleting back ferrule design expands on the already robust performance of the traditional ferrule design and provides:
- excellent gas-tight sealing and tube-gripping action
- easily achieved proper installation
- consistent remakes
- excellent vibration fatigue resistance and tube support
- full compatibility with original Swagelok stainless steel tube fittings of identical sizes.
Cleaning and Packaging
Fitting components are cleaned to remove machine oil, grease, and loose particles. For more information, see Swagelok Standard Cleaning and Packaging (SC-10). Fittings are available individually bagged.
On request, fittings can be cleaned and packaged in accordance with Swagelok Special Cleaning and Packaging (SC-11) with front ferrules silver plated and Krytox® 240 AC applied to the internal surface of the nut.
Options and Accessories
Replacement parts, including nuts, ferrules, nut-ferrule sets, and ferrule sets are available.
Gap inspection gauges, depth marking tools, bulkhead retainers, inserts for soft plastic tubing, preswaging tools, and hydraulic swaging units are available.
