 Conduits are connected in a circuit, and can move items from their

+Filtering of items can be done by placing an item into a filter slot and

+Conduits also act as a digilines conductor. If the hopper mod is loaded,

+the bottom. Be aware that hoppers from the hopper mod have some deficits
+that can cause some nodes from this mod to not function correctly in
+multi-player environments. The hoppers from this mod are more compatible.
 Pipeworks tubes can push items into and pull items from the inventory.

+Note that if a sending conduit is moved (as with a piston) while in the
+process of sending items, when the conduit is moved back into a circuit
+a duplicate of the last sent item/s can be resent.
