6 Fittings The Swagelok Fitting dvantage TUB Over fittings and not a single leak. Messages from customers credit Swagelok components and tube fittings, along with Swagelok distributor support, as having played a major role in helping them succeed. Swagelok continues to improve the performance and reliability of the tube fitting for use in thousands of diverse applications including research, alternative fuels, analytical and process instrumentation, oil and gas, power, petrochemical, and semiconductor industries and addressing such critical issues as: gas-tight seal vibration (tube grip) thermal shock compliance with industry standards installation corrosion intermix/interchange. Gas-tight Seal xcellent sealing and consistent reassembly help ensure accurate measurements of process parameters air, steam, fuel, and water to keep your plant operating efficiently. Moreover, Swagelok tube fittings minimize fugitive emissions, as well as process fluid leakage and operation costs. Contact your authorized Swagelok sales and service representative for more information about Swagelok nergy missions Surveys or to schedule a survey. Vibration ( Grip) The patented case-hardening process and back-ferrule geometry provide excellent vibration fatigue resistance and tube support even in harsh or stressful environments, such as hydrocarbon processing, on-vehicle applications, or rotary equipment applications. Swagelok has conducted vibration tests, which show that the Swagelok tube fitting with advanced geometry hinging-colleting back ferrule isolates and protects the stress riser that is generated along the tube during the gripping part of assembly. The colleting portion of the back ferrule allows more material to contact the tube, for additional support. This colleting action enhances gripping performance and provides both direct and axial support to the gripping function. This design minimizes the effects of bending deflection at the point of grip on the tubing. Contact your authorized Swagelok representative for more information about vibration test reports. Used exclusively on our equipment and has proven to be very reliable and easy to mainta I have used Swagelok fittings from when I was a technician through today in my role in facility management. Would recommend them for any use.

TUB Typical lignment Problem When installing pipe elbows or tees, it is often difficult to align the fitting with the desired run.. In this example, the installation requires connecting tubing to a female end connection. 2. When the pipe connection is tightened, the male elbow points in the wrong direction for the desired run. Loosening the pipe connection could mean leakage at the pipe thread. Swagelok Solution By using a Swagelok tube adapter in conjunction with a union elbow or tee, these difficulties can be avoided. 3. Tighten the pipe connection of a Swagelok male adapter into the female end connection. 4. Connect a Swagelok union elbow or tee to the adapter by tightening the Swagelok tube fitting with a wrench, while holding the elbow or tee in the desired direction. Insert the tubing into the other end of the Swagelok elbow or tee and install the fitting. Swagelok tube adapters are to be used ONLY in Swagelok tube fittings. Use in fittings made by other manufacturers may result in leakage or slippage. Refer to Installation Instructions, beginning on page 2.

62 2 Fittings TUB Gaugeability On initial installation, the Swagelok gap inspection gauge assures the installer or inspector that a fitting has been sufficiently tightened. Position the Swagelok gap inspection gauge next to the gap between the nut and body. If the gauge will not enter the gap, the fitting is sufficiently tightened. If the gauge will enter the gap, additional tightening is required. lways depressurize a system before adjusting the tightness of a tube fitting connection. Installation Instructions Swagelok tube fittings /25 mm and smaller can be installed quickly, easily, and reliably with simple hand tools. Over /25 mm sizes require use of a hydraulic swaging unit to swage the ferrules onto the tubing. Safety Precautions o not bleed system by loosening fitting nut or fitting plug. o not assemble or tighten fittings when system is pressurized. Make sure that the tubing rests firmly on the shoulder of the tube fitting body before tightening the nut. Use the correct Swagelok gap inspection gauge to ensure sufficient pull-up upon initial installation. lways use proper thread sealants on tapered pipe threads. o not mix materials or fitting components from various manufacturers tubing, ferrules, nuts, and fitting bodies. Never turn fitting body. Instead, hold fitting body and turn nut. void unnecessary disassembly of unused fittings. Use only long reducers in female Swagelok end connections. See the instructions starting on the next page for installation of Swagelok tube fittings, O-seal male connectors, caps and plugs, port connectors, tube adapters, positionable elbows and tees, weld fittings, depth marking tool, and preswaging tool. Tubing Considerations Metal tubing material should be softer than fitting material. For example, stainless steel tubing should not be used with brass fittings. When tubing and fittings are made of the same material, tubing must be fully annealed. lways use an insert with extremely soft or pliable plastic tubing. xtremes of wall thickness should always be checked against the suggested minimum and maximum wall thickness limitations. Surface finish is very important to proper sealing. Tubing with any kind of depression, scratch, raised portion, or other surface defect will be difficult to seal, particularly in gas service. Tubing that is oval and will not easily fit through fitting nuts, ferrules, and bodies should never be forced into the fitting. See Swagelok Tubing ata (MS-0-07) for more information about tubing selection.
