Thermo Fisher, 6040.2375, Viper™ Fingertight Fitting Systems, Stainless Steel, 0.18 mm ID

Viper™ Fingertight Fitting Systems, Stainless Steel, 0.18 mm ID is designed for connecting analytical HPLC and UHPLC fluid pathways with a compact, low-dead-volume, tool-free connection. This version is a stainless-steel Viper capillary with a 0.18 mm internal diameter and 350 mm length. The ferrule-free fingertight connection minimizes additional dead volume where tubing meets a compatible column or valve, helping maintain peak shape and separation performance. The flexible stainless-steel tubing has an external diameter of 1/32 inch and is suitable for high-pressure fluidic service up to approximately 1,300 bar. The system can be used with a broad range of LC columns and valves, including narrow connection spaces such as multiport valves. It provides an alternative to conventional wrench-tightened fitting assemblies when repeated fluidic connections are needed during system configuration or method development. The 350 mm length is the key specification for routing a line between LC modules or from a valve to a column while keeping the specified 0.18 mm internal diameter. The fitting is supplied individually.
