A tank handle or cap is designed for the convenience of the consumer. One aspect of the invention cap allows the end user to determine at a glace and from a distance if the tank is full or empty based on color distinction and/or word imprints on different sides (halves) of the invention cap. The cap is removably securable to the tank in different orientations to effectively expose the telling side of the invention cap. This allows the user the ability not to have to go over to the tank and lift the tank to gauge if the tank is full or not. This will reduce the risk of possible back injury. Other design features include an easy-to-use grip and open and close directional indicators to allow clear and concise understanding and operation of tank valves.
