Agilent, 0100-2595, Ferrule, polyamide, graphite 1/32 inch, 5/pk

Agilent polyamide/graphite ferrules provide replacement sealing elements for the transfer-line interface on compatible 7697 and 8697 headspace samplers. The ferrules are specified for 1/32-inch connections and are supplied in packs of five. A correctly seated ferrule helps maintain a leak-tight gas pathway between the headspace transfer line and its mating interface during routine sampling. Use the ferrule size and material specified for the headspace interface rather than substituting a conventional inlet-column ferrule without confirming geometry and temperature suitability. Before maintenance, cool the relevant components, isolate gas flow when required and remove the worn ferrule without damaging the fitting surfaces. Install a clean ferrule in the prescribed orientation and tighten to the instrument procedure, avoiding excessive compression. Confirm transfer-line integrity with the designated leak-check procedure before introducing volatile test samples.
