Agilent G1999-80402 80403 Calibration & Gas Valves

Current Stock:

Product Description

Manufacturer: Agilent Technologies

Model: Does Not Apply

Condition: Used. Comes in non-original packaging. This assembly is in Good cosmetic condition, with just some minor scratches on the labels.  All the fittings look clean inside. Cosmetic appearance may vary slightly from pictured unit(s).

Notes: These parts have not been tested. The G1999-80402 was easy enough to find in the 5973/5975 inert Mass Selective Detector literature but the G1999-80403 not so much.  From our conversation with Agilent tech support, this valve looks like it is a subassembly of the G1999-60452 or G1999-60456 CI Calibration Valve Assembly without the o-ring, nipple, and glass vial, normally fitted on the compression fitting (shown in photo 4). The part number on the label is not in their system, according to them. No manuals, cords/cables, or additional items are included if not listed or shown.
