ABSTRACT:
A valve guard is mounted on a scuba air tank and includes a protective cap which envelops and shields the air tank regulator valve from damage and abuse during both storage and use of the tank. Flexible air hoses which are coupled to the regulator valve during use may freely pass through apertures provided in the cap. The apertures provide ready access to the regulator valve without requiring removal of the valve guard from the tank. The cap defines a handle for lifting the tank without requiring engagement of the regulator valve.
