    Let’s Talk About Fitting Basics…


    What we commonly call a “fitting” in the analytical instrument world really refers to a system comprised of a “nut” and a “ferrule.”

    The choice of which nut and ferrule to use in your system is dependent on several parameters:

    • Threads of the receiving port
    • Geometry of the receiving port
    • Size and type of tubing used
    • Material from which the port is made
    • Amount of pressure expected

    Wouldn’t it be great if all this information was contained on one chart to choose the proper fitting for your analytical application?

    We have updated our Periodic Table of Analytical Fittings. This table illustrates over 100 analytical fittings’ pressure rating, tubing size, head style, fitting material, and torque required.

    You have 2 choices. We have a digital PDF file available for you to download now below or you can request a printed poster by filling out the form.
