The Restek Flip Seal inlet seal is a special reversible type of dual Vespel ring inlet seal for the Agilent 5890/6890/7890 split/splitless GC inlet. With the one-time installation of a special reducing nut adaptor fitting (cat.# 23406), one seal can be “flipped” and used twice, unlike the typical seal used on the bottom of the inlet, which is only used once and then discarded.
