Inlet Liner O-Ring and Inlet Seals for Agilent (5890, 6890, and 7890)

Two commonly replaced consumables in an Agilent capillary injection port are the inlet liner o-ring, and the inlet seal. Inlet liner o-rings develop stress cracks over time, potentially allowing split gases to enter the carrier gas stream. Inlet seals must be regularly changed to prevent sample adsorption due to accumulation of sample residue and/or septum fragments.
