Safe working pressure is 500 psiG (STD) 1,000 psiG (optional).
Features
  • "Engineered Plastic" gauge front and optional stainless steel body bolts provide superior corrosion resistance in "over-the-road" trailers, outdoor or salt air environments
  • Dry gauge design with no internal liquid fill
  • Eliminates costly clean up from liquid fill leaking and fouling the tank and system
  • No gauge damage/accuracy loss caused by liquid fill expansion/contraction when exposed to temperature shocks in cryogenic applications
  • Up to a 30 lb. (14 kg) weight savings on liquid Helium and Hydrogen
  • Allows more products to be transported in mobile trailers
  • Easier and less labor to panel mount
  • Adaptable to a wide variety of mounting configurations
  • Ability to create custom dials for horizontal and vertical tanks
