ABSTRACT:
An indicating apparatus for measuring the pressure of a fluid within a container, such as a tire, which includes a housing adapted to be mounted on the tire valve assembly. A plunger is supported within the housing 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 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 apparatus without having to remove the apparatus from the tire valve assembly.
