Restriction Tube

This tube modifies which way your items will travel. For all intents and purposes, a Restriction Tube is

considered 5000 Pneumatic Tubes, so in most cases, items will not travel through this pipe unless either
 * All other valid destinations are full
 * You have 5001 Pneumatic Pipes leading to a chest for some reason.

This tube gets its name from the fact that any destinations connected to this pipe are restricted from any items entering it via pipe unless one of the above conditions are true. Basically, a stream of items will travel through a Pneumatic or Redstone Tube before travelling through this tube.
