The gas pressure for N-EVAP and MULTIVAP instruments must be between 5 and 20 psig. If the supply is greater than 20 psig, tubing may blow off the connectors. This regulator reduces inlet pressure from up to 300 psig to a variable output O to 30 psig. The output pressure is indicatedon a gauge. Connectors are 1/4 inch MNPT on the inlet and 1/4 inch compression tube fitting on the outlet. Other fittings are available. Please specify your requirements.
