Swagelok Tube dapters Solve lignment Problems s can help eliminate difficult alignment problems and can be used with any fitting. Typical lignment Problem When installing a gauge with a pipe fitting end connection, it is often difficult to align the dial to the desired position without damaging the gauge. 5 5 1 1 15 Swagelok Tube dapters Gauges with integral s eliminate alignment problems. 14 2 Installation Instructions 1. Insert the gauge with integral into a fitting. 2. lign the gauge dial to the desired position. 3. Install the fitting. s are to be used ONLY in fittings. Use in fittings made by other manufacturers may result in leakage or slippage.

Some items are available only as factory-installed options; others are available for field installation, as described below. djustable Pointers Gauges are available with adjustable pointers that allow resetting to zero. djustable pointers are standard for all P model gauges and are optional for B and S model gauges. Orifices Orifices are used to restrict flow, reducing the immediate effect of pulsations and pressure spikes. ll Swagelok industrial and process gauges are available with orifices as factory-installed options.

Internal components are cleaned in accordance with SME B4.1, Section 5, which states that the gauge shall be free of visually detectable moisture and foreign matter (chips, slivers, weld slag or splatter, shop soil, greases, oils, or other contaminants) that could be mechanically detrimental to proper function of the gauge. The gauge is then capped and bagged to maintain cleanliness. Certificates of Calibration This option provides the user with a calibration sheet and a serial-numbered gauge that has been calibrated with a gauge traceable to DKD for gauges manufactured in Germany or to NIST for gauges manufactured in the U.S. Certificates of calibration are available for all Swagelok gauges. Material Certifications This option provides the user with a General Material Certificate of Compliance, EN 124 2.2, stating that the gauges were manufactured from material purchased and certified as being in accordance with the specifications listed in this catalog. Material certifications are available for B, C, S, M, and L model gauges. Liquid Fill Liquid-filled gauges enhance the reliability and integrity of the measuring system for long periods under extreme operating conditions by dampening vibration and lubricating the gauge movement. B, C, S, and P model gauges are available liquid filled. Because the type of liquid used to fill the gauge may vary with the application, Swagelok offers glycerin, low-temperature glycerin, and silicone. It is important to choose the proper fill liquid based on the operating temperature and pressure. mbient Operating Temperature Temperature F ( C) Fill Fluid 4 to 14 ( 4 to 6) Unfilled 4 to 14 ( 2 to 6) Glycerin 29 to 14 ( 34 to 6) Low-temperature glycerin 4 to 14 ( 4 to 6) Silicone Operating Pressure (Dial Range) If the dial range selected is equal to or below 6 psi, 4 bar,.4 MPa, or equivalent, liquid-filled gauges must use low-temperature glycerin or silicone fill liquid to ensure fastest response and gauge accuracy. In addition, if a maximum indicating pointer is selected in a liquid-filled gauge, the fill liquid should be lowtemperature glycerin or silicone. Glycerin- and silicone-filled gauges cannot be used where strong oxidizing agents are present. Glycerin and low-temperature glycerin fill liquid are available as accessories for field installation.

22 Industrial and Process Pressure Gauges Options and ccessories Snubber Fittings Gauge Protectors Swagelok snubber fittings protect gauges and instruments from system pressure surges and shocks. Pressure damping (snubbing) is accomplished through the use of a porous sintered 316 stainless steel element. Installing a Swagelok snubber fitting upstream from the gauge reduces the gauge s response rate. The response rate generally varies with the initial pressure drop across the porous element of the snubber fitting and allows the gauge to reach line pressure smoothly. Snubber fittings should be used only to protect against pressure shocks, impulses, and surges. Systems requiring control of contaminants should use filters suited to the application. See the Swagelok Filters catalog, MS-1-92. Elements With five basic elements available, snubber fittings can meet the requirements of fluid applications ranging from light gases to liquids with viscosities above 1 SUS (Saybolt universal seconds) (22 cst [mm 2 /s]).
