PVC Gauge Guards

Protect Your Pressure or Vacuum Instruments From Clogging, Corrosion and Damage!
Gauge Guard Image We offer this high quality gauge guard with or without a pressure gauge.  If you want to know the operating pressure of your system or any piece of equipment attached, it is highly recommended that you use a gauge guard.

If you get the unit without a pressure gauge you will need to use sterilized mineral oil to fill the gauge and gauge guard.

Features and Advantages:

  • Diaphragm Seals provide a protective barrier between process fluid and the pressure/vacuum gauge or instrument.
  • Prevents your gauges from clogging with calcium or other particulate.
  • Keeps your gauges from leaching copper into your aquarium water.
  • Compact size makes these isolators ideal for limited-space installations.
  • +-4% accuracy. Will handle most applications.
  • Simple to fill and install.
  • Hermetically-sealed unit-body construction - molded body avoids possibility of dangerous leaks.
  • For use with highly aggressive or ultra-pure liquids.
  • Diaphragm safety - If the gauge or instrument fractures or is removed from the guard while the system is pressurized, the diaphragm will automatically seal against leakage to the atmosphere.
  • Glass-filled Polypro bodies for excellent chemical compatibility and temperatures to 185 degrees F (85 degrees C).
