Model GP401 is a brass single-stage regulator with a neoprene diaphragm for general purpose applications where a slight rise in delivery pressure from a full to near empty cylinder can be tolerated. The Model GP401 is not recommended for high-purity applications that may be sensitive to contamination due to elastomeric components.
