An indicator for gases, essentially constituted by a circular capsule whose base has a threaded extension, axially drilled by a conduit that communicates with the internal chamber of the capsule itself, which is covered by an elastic membrane, and this subject to the edge of the capsule by a circular lid with a central extension provided with a hole, through which more or less a colored cylinder protrudes, according to the push experienced by the elastic membrane upwards by the pressure of gas entering through the central conduit of the capsule and which is counteracted by a helical spring established in the extension of the circular lid, so that when there is no gas the colored cylinder is completely hidden inside the lid, due to the action of the spring.
