Column End Fitting

Column end fittings are precision-machined connectors installed at both ends of a chromatography column (such as HPLC, UHPLC, or analytical chromatography tubing). Their main function is to securely connect the chromatography column to the flow path of the analyzer—such as the pump inlet, detector, or sampling system—while maintaining leak-free, high-pressure fluid sealing.   Typical Thread / Tubing Compatibility: 1/16" OD tubing (most common for HPLC) Thread standard often: 10-32 UNF Internal surface designed to minimize dead volume
