The 'Every Drop' uses a 1/2" stainless steel dip tube that is angled so that it can pick up every last drop from your kettle. The unique silicone bushing threads onto the interior side of your coupler and allows the dip tube to be angled anyway you so desire.
Want to use a different sized dip tube? No problem! The silicone bushing can be used with any 1/2"OD dip tube.
