Abstract of the Disclosure An indicating apparatus for measuring the pressure of a fluid within a container, such as a tire, which includes a housing having one end adapted to be mounted on the tire valve assembly. The housing has a range of scale indicia thereon extending from a minimum valve to a maximum valve representative of the pressure of the fluid within said container between a predetermined range of pressure. A collar is mounted onto another end of the housing, and a sleeve is supported within the housing having opposite clamping ends that secure the collar in nested relation to the housing. A plunger is supported within the sleeve for movement between an inoperable position wherein the tire valve is closed and a first operate position wherein the valve is opened to permit fluid from the tire to enter the housing. An indicator piston is supported within the housing for movement to an indicating position relative to said scale indicia to provide a reading representative of the pressure within the tire, which position is exposed to view through the housing. The apparatus further provides for movement of the plunger to a second operate position wherein the valve is opened to permit pressure from an external source to be transmitted to the tire through the housing without having to remove the apparatus from the tire valve assembly.
