Agilent, G3138-65129, Plug for cross joint, 3/pk

Agilent cross-joint plugs are small fluid-path components used to block a selected line in the internal-standard mixing arrangement of compatible ICP-MS systems. They are intended for the grounded internal-standard T-joint with earth block G3280-67062, where either an internal-standard or sample channel may need to be closed. This configuration contains three plugs. The plugs support instrument setup, servicing, and reconfiguration of sample introduction plumbing without requiring replacement of an entire T-joint assembly. The associated fluidic architecture is found across a range of Agilent ICP-MS platforms, including the 7500 through 8900 families. Proper installation helps prevent unwanted air intake or fluid loss when a branch is intentionally isolated.
