The adapter from Black Leaf has diffuser slits and transforms bongs with grinding SG 19 into grinding SG 14, so SG 14 bowls can be used. It is made of stable borosilicate glass and has an inside cut, so it fits almost completely in the 19er grind and closes tight. So bowls are not higher placed as they are without adapters
