DP0V-2FBA (125 psi / 8.6 bar) pump, 1/4" female NPT gauge adapter, 3ft hose, 1/4" MNPT process connection. The ideal solution for very precise low pressure calibration or differential pressure testing using an external pressure calibrator as the reference. This light weight, compact pump generates up to 125 psi (8.6 bar) with ease. Its large-volume, fine-adjustment piston provides precise control, even at very low pressures.
