Abstract
Device for checking the escape of air from a valve essentially characterized by being constituted by a container in which an advantageously porous deformable block is contained which is impregnated with a foaming substance further comprising a separate retractable stem subsidiaryly combined with a spring which stem it acts on the aforementioned block releasing foam from the latter and because the retractable stem itself has an axial cavity into which the foam released by said porous block is introduced, said cavity of the stem being operatively arranged to receive at least the mouth of a valve on which deposits therefore the foam that allows to check the escape of the fluid.
