Hi. My Aqualung Impulse Cryo second stage leaks. When I took it apart I found out that the poppet (27b, part 107826) is broken so the actual LP seat does not make a seal (see picture). Unfortunately very few Aqualung second stages seem to have the same part (Impulse, Impulse Octo and Impulse Cryo EAN) but none of the many other Aqualung second stages uses that part (it is different in Glacia, Titan, Cousteau, Calipso, Micro). Any idea if other second stages from other brands use this poppet? Any one has a clue where to find such part? I know that it is pretty much a lost cause but this is what makes it fun, the impossible search for a 10 buck part that will eventually cost much more.
