Gauge Guards are an economical way to protect instruments from corrosion and clogging -- or to protect your process from the instrument.

Plast-O-Matic True Blue Brand Gauge Guards maintain high accuracy, and assure system dependability within an operational range of full vacuum to 250 PSI, 200 PSI for Series GGME and GGMU.
•  Offers an inexpensive initial investment.
•  Reduces instrument failures.
•  Reduces system downtime.
•  Eliminates the expense of special alloy instruments.
•  Choice of various thermoplastic materials assures maximum process compatibility.
•  Every single Gauge Guard is individually inspected and hand tested.

Gauge Guards are used to isolate and protect pressure or vacuum instruments used on ultra-pure or highly-corrosive fluid lines. They can be confidently used with liquids such as deionized water (GGMU) sulphuric acid, hydrochloric acid, caustics...or with gasses such as corrosive air, ammonia...whenever such fluids will corrode metal instrument components. Gauge Guards also protect against clogging of instruments by suspended solids or highly viscous fluids. Furthermore, they eliminate dead pocket areas within instruments where chemicals or organic matter could decompose. All True Blue Gauge Guards are available with or without gauges.
