ABSTRACT:
Disclosed is an indicator system for use with inflating devices that use a cylinder of compressed gas. The indicator system is comprised of a cylinder adapter which receives and supports a cylinder and, concurrently, is received by an inflating device. The cylinder adapter includes an indication means that signals whether the attached cylinder is full or has been discharged by way of the indication means being responsive to the high pressure release from the cylinder during a discharge. The indication means incorporates the use of the color green to signify that the cylinder is full and the color red to signify that the cylinder has been discharged. The indicator system is designed to have a one-time use after which it is disposed of.
