Compact gauge guard for corrosive liquids

January 10, 2006
All-thermoplastic, compact gauge guard for corrosive liquids is now available. Series GGME is a compact, 1-3/8-inch-high seal that isolates gauges and other instruments from a chemical process. The barrier seal transmits pressure with an accuracy of ±4 percent. The compact size is ideal for space-limited applications. Design is based on an ultrasonically-welded, uni-body construction with a natural polypropylene connection on the process side. This design prevents occurrence of dangerous leaks, and precludes rupture of the diaphragm seal even if the gauge is accidentally removed. Polypropylene provides excellent chemical compatibility and is suitable for process temperatures to 185 degrees F.
