ABSTRACT:
A one-piece weather cap that can be installed or removed from a gas valve without the aid of tools, with the one-piece weather cap having a flexible and resilient neck with dimples and a circular band that frictionally engage an extension on the gas valve to frictionally hold the weather cap on the gas valve during adverse weather conditions, with an annular skirt that extends in a cantilevered fashion radially outward from the neck to protect the gas vent in the valve from becoming obstructed with snow or ice.
