These finger-tight capillary column nuts made from high-quality stainless steel are an alternative to conventional column nuts. These fittings work best with graphite type ferrules and help prevent over tightening, which can cause graphite material to exude into the inlet.

• Allow wrench-free column installations
• Available for standard (1,58 mm) and compact (Agilent-style) ferrules

These fittings can be installed by hand without a wrench and cool down much faster than conventional fittings, making column and inlet maintenance easier.
