 Waterproof CNG Pressure Gauge 


Waterproof CNG Pressure Gauge is fixed on the intake valve between cylinder and pressure reducing 

regulator of CNG vehicles to show the pressure of natural gas in cylinder. 

Through a gas pressure sensor inside, the gauge sends pressure signal to fuel changeover switch, 

so that the driver get to know the gas volume inside cylinder. 

Waterproof CNG Pressure Gauge owns patented waterproof craft, avoiding water inflow when you are washing you car, 

so that the gauge can be used longer.
