Connector, SilTite u-Union, 0.32-0.32 mm ID, for Restek or Standard Columns

Press-fit style connectors work well for many applications, but the connector seal can be broken by extreme temperature and pressure cycling. In these situations, SilTite ?-Unions are a better alternative as they create a permanent connection between analytical columns, guard columns, and retention gaps. SilTite FingerTite technology provides easy installation and a reliable, leak-tight connection. Data quality can be improved by using these connectors because their zero-dead-volume design and deactivated metal construction ensure optimal peak shapes. Robust SilTite ?-Unions are recommended for mass spectrometry work and any application with extreme temperature and pressure changes. Connector kits are available in six configurations that are designed to securely connect columns of either the same or different inner diameters. Each kit contains two SilTite µ-Union connectors, five double-taper ferrules, and installation tools.

When connecting columns of different inner diameters (ID), always connect the column with the largest ID first. The ferrules are very small, making it difficult to see the size difference between the two ferrule orifices and making it easy to install the smaller ID column into the wrong orifice. Since the larger ID column (e.g., 0.32 mm) will not fit into the smaller ferrule orifice (e.g., 0.25 mm), installing the larger column first ensures the correct end of the ferrule will be used for both columns.
