Restek offers several choices. The Defined PressFit connectors and Press-Tight connectors are glass connectors with a tapered internal diameter at each end and are the quickest and least expensive option. The SilTite μ-Union connectors are another alternative; these connectors are constructed of deactivated metal and provide easy installation and a zero-dead-volume, permanent, leak-tight connection, which makes them ideal for use with mass spectrometers. A popular and effective option is the MXT-Union connector, which will not break and ensures low dead volume.
Our Vu2 Union connector and SeCure “Y” connector combine the simplicity of a Press-Tight connector with the strength of a metal union and can be used to a temperature of 400 °C.
