Forgotten..the scary part is co2 in higher temps..basically the only other penetrating mass is the foster adapter at. 375 but sitting on a flush surface ..in other words the thread will only be as deep as the Foster will fit..the rest being a pinhole (>.100) for the gaseous exchange ..i wouls not allow the ful 3/8 rear face of the foster to take load in this method..seeing as how i would not trust the threading to restain the force long term.
