Gauge guards

Plast-O-Matic Valves announces an improved plastic gauge guard, also known as diaphragm seals or instrument isolators, designed to protect gauges and other instruments from corrosive liquids in processes to 250 psi. Flexing diaphragm characteristics and a large sensing area provide immediate response to changes in pressure or vacuum and are accurate to three percent. Series GGM guards are available with or without gauges in PVC, Polypropylene or PVDF with PTFE or FKM diaphragm. Instrument connection sizes are 0.25″or 0.5″ (6.35 or 12.7 mm) NPT with 0.5″ (12.7 mm) system connection. http://www.plastomatic.cominfo@plastomatic.com
