Dual read gauges 100/1680 or 160/2120 (psi/gpm)  
  • Model; SG-P66916LF
    • 4” Gauge160 psi / 2120 gpm
    • High Quality Liquid Filled Gauges.
    • Glycerine in the Gauge dampens needle oscillation and allows to take more accurate flow readings.
    • Make certain that the Gauge is never allowed to Freeze.
    • Do not Over Pressurize the Gauge. Choose a Gauge so the maximum pressure will not exceed 80% of the Gauge limit.
