brass materia lpg gas pressure gauge 

oil pressure gauge oil pressure gauge has good vibration proof performance apart from the normal gauge performance.It is especially applicable under the conditions of mechanical vibration and pressure pulsation to measure the pressure of media such as the gas and the steam which is not corrosive to cooper alloy and has neither crystallization nor precipitation. Main Technical Data Ambient temperature:  -40℃~+ 70℃ (unfilled case), -20℃ ~ +60℃ (case filled with glycerol), -40℃~+70°C(case filled with silicone oil ) media temperature max+ 100℃ (fluid-filled case) Temperature performance…
