The Goulet listing mentions that the transparent (non-actylic) models can be eyedroppered. Does anyone know what size the O-ring you install should be? I tried one of the O-rings that I use on my Preppies, and it stuck out too far and blocked the cap. Should I just try it with silicone grease and no O-ring?
you mean like what I do with mine as shown - in this previous post - you need an O ring that is sized roughly the same diameter ( or sliver smaller than the threaded portion of the section ) and it need to be a thin type ( not the very round and bulged out type )
