8 INTERMIXING/METRIC TUBE FITTINGS Intermix/Interchange with Other Manufacturers Components This practice can be dangerous. Leak-tight seals that will withstand high pressure, vibration, vacuum, and temperature changes depend on close tolerances and consistent, exacting quality control in conjunction with good design principles. The critical interaction of precision parts is essential for reliability and safety. Components of other manufacturers may look like Swagelok tube fitting components but they cannot be manufactured in accordance with Swagelok engineering standards, nor do they benefit from innovations in design and manufacture defined by 36 active Swagelok tube fitting patents issued since 989. Metric Swagelok Fittings Metric tube fittings have a stepped shoulder on the body hex. Swagelok metric tube end Swagelok fractional tube stub Stepped identification shoulders No shoulder Swagelok metric tube ends Stepped identification shoulders Shaped fittings, such as elbows, crosses, and tees, are stamped MM for metric tubing and have no step on the forging. 8

9 INSTALLATION INSTRUCTIONS 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 Do not bleed system by loosening fitting nut or fitting plug. Do not assemble and 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. Always use proper thread sealants on tapered pipe threads. Do 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. Avoid unnecessary disassembly of unused fittings. Use only long reducers in female Swagelok end connections. See the instructions starting below 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. 9

10 INSTALLATION INSTRUCTIONS Swagelok Fittings Up to /25 mm These instructions apply both to traditional fittings and to fittings with the advanced back-ferrule geometry. Fully insert the tube into the fitting and against the shoulder; rotate the nut finger-tight. High-pressure applications and high safetyfactor systems: Further tighten the nut until the tube will not turn by hand or move axially in the fitting. Mark the nut at the 6 o clock position. While holding the fitting body steady, tighten the nut one and onequarter turns to the 9 o clock position. For /6,, and 3/6 ; 2, 3, and 4 mm tube fittings, tighten the nut threequarters turn to the 3 o clock position. 0

11 INSTALLATION INSTRUCTIONS Swagelok Fittings Over /25 mm. Preswage the ferrules onto the tube using a Swagelok multihead hydraulic swaging unit (MHSU). 2. Apply the lubricant packaged with the fitting lightly to the body threads and the rear surface of the back ferrule. 3. Insert the tube with preswaged ferrules into the fitting until the front ferrule seats against the fitting body; rotate the nut finger-tight. 4. Mark the nut at the 6 o clock position. 5. While holding the fitting body steady, tighten the nut one-half turn to the 2 o clock position. Use the Swagelok MHSU gap inspection gauge to ensure that the fitting has been tightened sufficiently. 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. Always depressurize a system before adjusting the tightness of a tube fitting connection.

12 INSTALLATION INSTRUCTIONS Swagelok Fittings Reassembly All s You may disassemble and reassemble Swagelok tube fittings many times. Always depressurize the system before disassembling a Swagelok tube fitting. Prior to disassembly, mark the tube at the back of the nut; mark a line along the nut and fitting body flats. Use these marks to ensure that you return the nut to the previously pulled-up position. Insert the tube with preswaged ferrules into the fitting until the front ferrule seats against the fitting body. Over /25 mm sizes: If needed, reapply lubricant lightly to the body threads and the rear surface of the back ferrule. While holding the fitting body steady, rotate the nut with a wrench to the previously pulled-up position, as indicated by the marks on the tube and flats. At this point, you will feel a significant increase in resistance. Tighten the nut slightly. Do not use the Swagelok gap inspection gauge with reassembled fittings. 2

13 INSTALLATION INSTRUCTIONS O-Seal Male Connectors. Turn the O-seal connector into the female end until it is finger-tight. 2. Tighten the O-seal connector until it makes metalto-metal contact with the face of the female end. 3. Tighten slightly with a wrench. O-rings are coated with a thin film of silicone-based lubricant. Removal of factory-applied lubricants may alter performance. Caps and Plugs Caps See Swagelok tube fitting installation and reassembly, page 0 and 2. Plugs While holding fitting body steady, tighten the plug one-quarter turn from the finger-tight position. For /6,, and 3/6 ; 2, 3, and 4 mm tube fittings, tighten the plug one-eighth turn. For over and over 25 mm tube fittings, tighten the plug one-quarter turn. Reassembly You may disassemble and reassemble Swagelok plugs many times. Make subsequent connections by slightly tightening with a wrench after snugging the nut by hand. Pipe Thread Fittings A thread sealant should always be used when assembling tapered threads. SWAK anaerobic pipe thread sealant, PTFE-Free pipe thread sealant, and Swagelok PTFE Tape are available. For more information, see the Swagelok Leak Detectors, Lubricants, and Sealants catalog, MS

17 INSTALLATION INSTRUCTIONS Adapters Reassembly See Swagelok tube fitting reassembly, page 2. Weld Fittings Welding Precautions for Swagelok Fittings with Weld End Connections. Remove the nut and ferrules. 2. Turn a Swagelok tube fitting plug or another nut onto the fitting so that it is finger-tight. This protects the threads and sealing components. 3. Provide a suitable heat sink to dissipate the heat. 4. Tack weld at four positions 90 apart to hold the fitting in place and to ensure alignment and concentricity of the components. 5. Complete the weld. 6. Remove the plug or nut and replace the nut and ferrules. Caution: When welding carbon steel fittings, the heat often removes the protective oil from the threads. It is important to apply another lubricant, such as Goop thread lubricant. Depth Marking Tool. Insert cleanly cut, fully deburred tube into the depth marking tool (DMT) until the tube is against the shoulder of the tool. Using a pen or pencil, mark the tube at the top of the DMT (Fig. ). Fig. Fig Remove the tube from the DMT and insert it into the Swagelok fitting until it is against the shoulder of the fitting body (Fig. 2). Rotate the nut fingertight. If any portion of the mark on the tube can be seen above the fitting nut, the tube is not fully inserted into the fitting. 3. While holding the fitting body steady, follow Swagelok tube fitting installation instructions, page 0. 7

18 INSTALLATION INSTRUCTIONS Preswaging Tool. Install the Swagelok nut and ferrules onto the preswaging tool. 2. Insert the tube into the preswaging tool. 3.

21 TUBING Tubing Installation Tubing properly selected and handled, when combined with the quality of Swagelok fittings, will give you leak-tight systems. Properly installed on such tubing, Swagelok fittings provide reliable service under a wide variety of fluid applications. When installing fittings near tube bends, there must be a sufficient straight length of tubing to allow the tube to be bottomed in the Swagelok fitting (see tables below). R L T T L Required straight tube length (see table) R Radius of tubing bend Fractional, T L➀ /6 23/32 3/6 3/6 5/6 7/8 5/6 3/6 5/8 7/8 5/ / ➀ Required straight tube length. Metric, mm T L➀

22 TUBING Tubing Selection 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. Always use an insert with extremely soft or pliable plastic tubing. Extremes 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. Gas Service Gases (air, hydrogen, helium, nitrogen, etc.) have very small molecules that can escape through even the most minute leak path. Some surface defects on the tubing can provide such a leak path. As tube outside diameter () increases, so does the likelihood of a scratch or other surface defect interfering with proper sealing. The most successful connection for gas service will occur if all installation instructions are carefully followed and the heavier wall thicknesses of tubing on the following tables are selected. A heavy-wall tube resists ferrule action more than a thin-wall tube, allowing the ferrules to coin out minor surface imperfections. A thin-wall tube offers less resistance to ferrule action during installation, reducing the chance of coining out surface defects, such as scratches. Within the applicable suggested allowable working pressure table, select a tube wall thickness whose working pressure is outside of the shaded areas. 22

23 TUBING Fractional Carbon Steel Tubing Allowable working pressures are calculated from an S value of psi (08.2 MPa) for ASTM A79 tubing at 20 to 00 F ( 28 to 37 C), as listed in ASME B3.3.

105 REPLACEMENT PARTS Nuts Knurled Female The Swagelok knurled nut tube fitting provides a leak-tight seal without the use of inserts on most wall thicknesses of polyethylene tubing. Inserts may be required for larger sizes. To set the ferrules on the tubing, initial connections must be made with a wrench, tightening the nut one and one-quarter turns from finger-tight (threequarters turn for /6, and 3/6 ; 2, 3, and 4 mm fittings). Leak-tight connections may be reassembled with finger-tight assembly. To order a knurled nut, add K to the female nut basic ordering number. Example: B-402-K To order a knurled nut on an assembled fitting with nylon ferrules, add KN to the fitting ordering number. Example: SS KN To order a knurled nut on an assembled fitting with PTFE ferrules, add KT to the fitting ordering number.
