Product Summary

  • Not valved
  • All stainless-steel construction
  • Regulated pressurized nitrogen cylinder pressurizes container inside cabinet to dispense solvent at low pressure out of cabinet
  • Can be used for vacuum or pressure venting containers inside cabinets
  • Factory installed and FM-Approved with purchased safety cabinet


The pass-through kit (model 25974) can be used on the sides or back of flammable liquid safety cabinets. This unique system provides a means to dispense solvents with pressurized nitrogen through the wall of a cabinet, if a pressure nitrogen assist from an outside source is needed. It can also be used for vacuum or pressure venting containers inside the cabinet. The stainless-steel construction without a check valve allows flow in either direction. A ¼-in NPT (tapered) fitting is required to thread into both sides of the pass-through. Only install on the sides and back of the safety cabinet, never on the doors, bottom or top of a cabinet.

Factory installed—must be ordered with cabinet.

Note: This TechTALK has guidelines for ordering factory-installed pass-through kits for Justrite safety cabinets to maintain FM approval and our 10-year warranty.
