purpose laboratory applications. The GP 402 maintains a constant
delivery pressure from full to near empty cylinder conditions.
The GP 402 is not recommended for applications sensitive to contamination due to its elastomeric components.
The Model GP 402 is suitable for:
  • Non-corrosive industrial grade gases
  • Purging
  • Pressure testing
  • Gas shielding
