Redstone Tube

A variation on the Pneumatic Tube is the Redstone Tube. It acts as a tube and Red Alloy Wire in one. Redstone Tubes are very handy for reducing wiring clutter, particularly in tight spaces. Use a Jacketed Wire to connect a Redstone Tube to a Red Alloy Wire on a floor, wall, or ceiling.

Note that along with the space saving there is a slight cost saving as well—using a Redstone Tube is cheaper than using a separate piece of Red Alloy Wire by 1/4 of an Iron or Copper Ingot per piece.
