- This page is about Filtered Essentia Tube from Thaumcraft 4. For other uses, see Filtered Essentia Tube.
The Filtered Essentia Tube is a block added by Thaumcraft 4. It is used to allow specific types of essentia to flow through it. This can be configured by using a Jar Label on it.
Filtered essentia tubes work like normal tubes, except it is possible to mark them with labels. When marked they will restrict essentia flow through them to what they have been marked with.
Shift-clicking on them with an empty hand will remove the label.
Restricted essentia tubes work like normal tubes, except they halve the any suction passing through them.
Directional essentia tubes only accept suction from one direction. The blue markings indicate the direction from which suction will be accepted.
