A brass single stage regulator with a neoprene diaphragm for
general purpose laboratory applications where a slight rise in
delivery pressures from full to near empty cylinder can be tolerated.
The GP 401 is not recommended for applications sensitive to contamination due to its elastomeric components.
The Model GP 401 is suitable for:
  • Non-corrosive industrial grade gases
  • Purging
  • Pressure testing
  • Gas shielding
