8004-0201, Agilent liner o-ring for Varian/Bruker, non-stick fluoroelastomer, 1177 split/splitless, 6.3/6.5 mm od, 10/pk

The Agilent non-stick liner O-rings are sealing consumables for compatible Varian and Bruker gas chromatograph 1177 split/splitless inlets. The fluoroelastomer rings are intended for inlet liners with nominal 6.3 or 6.5 mm outer diameters and are supplied in a pack of ten. Their function is to seal the liner-to-inlet interface while allowing the liner to be replaced during scheduled maintenance. O-rings exposed to high temperature, reactive residues or repeated liner changes can develop compression set, surface damage or contamination. Inspecting these seals helps reduce inlet leaks and supports consistent carrier-gas flow during injection. These components must not be confused with Agilent-specific inlet base seals, GC column ferrules or other 1177 inlet variants. Confirm the installed liner diameter and inlet model before fitting a replacement. Install a clean O-ring without stretching or cutting it, follow the approved inlet reassembly procedure and perform a leak check before analytical operation.
