Abstract
A compressed air indicator includes a housing having a pair of fittings and at least one (1) external pressure status window. The housing allows an 'in-line' connection to an air line allowing compressed air to pass through. Once connected, movable indicator sleeves within the housing are visible through any window. The indicator sleeves are acted upon and correspondingly positioned relative to each window based upon 'pressure' or “no-pressure” conditions within the air line and the housing.
