Improved pressure gauge, characterized in that the axial hole of the central block supporting the assembly communicates near the upper end, with a radial conduit through which communication is established with the internal cavity of the end secured to the central block described, of a profile tubular flat spirally wound on the central block, which has its most developed end blinded, where an indicator needle is mounted that adopts the appropriate bends, to be assembled by a point on the periphery of the scale in circular form, indicating the measured pressure, this scale is determined by its center, with the central block, to which it is screwed.
