<p>A vent cover for gas pressure regulators exposed to adverse weather conditions wherein the vent cover is mounted upon the vented neck of a gas regulator and is rotatably adjustable relative to the neck such that a vent opening defined in the cover may always be oriented downwardly regardless of the horizontal orientation of the regulator neck during installation. The downward orientation of the vent cover opening removes the possiblity of the regulator venting being rendered inoperable due to adverse weather conditions, such as icing.</p> |
