The Pneumatic Tube is RedPower 2's method of transferring items from one point to another. Items move considerably faster through Pneumatic Tubes than through BuildCraft Pipes (that is, pipes that do not have Golden Transport Pipes at intervals to speed up items) and do not require pipes at intervals to maintain item speed. By and large, Pneumatic Tubes function in the same way as BuildCraft Pipes. However, there are not more than one kind of Pneumatic Tube in RedPower as there are different types of pipes in BuildCraft. Functions such as sorting, item "gates" and so forth are performed by different RedPower machines. Also, Pneumatic Tubes cannot interact with some of BuildCraft's blocks and machines such as the Autocrafting Table or do not work well with them.
Instead of using Wooden Transport Pipes to move items out of a Chest or other inventory, RedPower utilizes Filters and Transposers to move items. Filters have the additional benefits of being able to assign a color to an item or group of items (Pneumatic Tubes can be painted so that they only accept items with specific colors assigned) as well as to only accept certain items from an inventory and to pull full stacks of items from an inventory. Transposers have none of these benefits and they can only pull items from an inventory one at a time.
If enough resources are available, Pneumatic Tubes can be replaced by Magtubes for faster item transport, although even Pneumatic Tubes are considerably faster than BuildCraft Pipes.
Feeding bees into an Inoculator with Pneumatic pipes can cause a multiplayer server to crash.
Pneumatic Tubes can transfer a redstone current when they are crafted into Redstone Tubes.
Where as a Pneumatic Tube normally selects the closest valid inventory to store items in, a Restriction Tube allows you to modify that behavior.
