Glycerine Filled Pressure Gauges

Shop durable glycerine filled pressure gauges (liquid-filled pressure gauges) for vibration-damped, reliable readings in demanding environments. Choose from popular dial sizes 40, 50, 63, 100 & 160 mm with bottom entry or back entry connections, covering ranges from -1 to +1000 bar (higher on request). Ideal for general industrial use with liquids or gases not highly viscous, not over 60 °C, and not corrosive to copper/tin alloys. Need stainless, chemical or hygienic seals? We can supply alternatives for aggressive media and sanitary processes.
