yeah, good idea - MIlk container is also ptex - I use it a lot for other stuff, should work here. Not sure about the tape though. Electrical tape is surprisingly 'spongy'. But I might try one wrap of telfon tape around the milkcontainer wrap to hold it in place while screwin in the cup.
Might be 'goodnuff' and certainly easier than heatgunning in some ptex.
let ya know how it works...
