Hazard

In the fuel pressure regulator of compressed natural gas vehicles, the valve seat dimensions and O-ring hardness in the high-pressure reducer are inappropriate, which may cause the O-ring to deform or rupture. As a result, fuel gas may leak from the safety valve to the exterior while remaining at high pressure as it flows into the low-pressure reducer.
