The T-Junction is a structure which consists of 3 pipe entrances. It is necessary to use either the T-Junction or the Four-Way to create a piped iridium network of more than 2 structures.


The T-Junction is used to branch a piped iridium network so that more structures may be connected to it. With one pipe leading into it, it can split the pipe into two. This is essential for creating large iridium networks. However, it is almost always preferable to build a Four-Way instead, as it has an extra entrance at the cost of a slight increase in volume and price.


Placing of the T-Junction is comparable to the Pipe. When being placed, it will snap to open pipe entrances, allowing for secure connections. It is notable that the T-Junction does not need to be placed snapped to a pipe entrance.

Pros and Cons


  • Expands iridium networks
  • Useful for connecting many smaller structures
  • Has a smaller volume and cost than the Four-Way


  • Has one less entrance than the Four-Way
