If your TubieeGo™ insert has arrived, and you are finding that your bottle is not fitting snuggly, it may be because your insert needs to be rethreaded. TubieeGo™ inserts have been designed to be rethreaded easily, as your bottle type may change.
There are three different ways to thread a TubieeGo™ insert:
STAR shape (the most common way of threading, and good for the majority of bottle types)
PARALLEL HORIZONTAL (this way of threading is good for Nutricia 500ml bottles, and small sterifeed bottles)
PARALLEL VERTICAL (this is only for Fresenius-Kabi feed bags)
