Pressure indicator for fluid installations, which consists essentially of a box divided internally in two chambers by an elastic membrane, in one of whose chambers a hole communicates with the installation of the fluid, next to the mouth whose hole is provided small protrusions in the manner of stops of the membrane, while in the opposite chamber is mounted a sliding sleeve as a plunger on the inside of a tubular neck in which the latter chamber extends and on whose bushing acts a spring tending to keep it constantly supported against the membrane, said bushing being of an indicator rod capable of exiting to the outside through a suitable opening when said bushing is displaced due to the pressure of the fluid and overcoming the action of the spring.
