8005-0916, Agilent seal pack rebuild kit with needle, for Waters 2690/2690D/2695/2695D, similar to WAT271019

The Agilent seal pack rebuild kit with needle is an HPLC autosampler maintenance assembly for compatible Waters 2690, 2690D, 2695 and 2695D systems. It is intended to service the sample introduction and seal-pack area where worn seals or needle components can contribute to leakage, injection-volume variability or carryover. The seal pack is a compatible maintenance alternative for the listed Waters autosamplers, but interchangeability must still be checked against the installed instrument revision. Before ordering, verify the installed autosampler model and the exact mechanical configuration. Replace the components under the instrument service procedure while protecting sealing surfaces from scratches or particles. Reassemble with suitable handling tools, prime the sample flow path and check for leaks before returning the autosampler to use. Performance verification should include appropriate wash steps, injection reproducibility and carryover checks with a suitable test mixture. This product is a maintenance kit, not an HPLC column or an autosampler vial set.
