Kinesis Pipe

Kinesis Pipes are a class of pipes from BuildCraft that transport Redstone Flux (RF). They are created by combining the original Transport Pipe with Redstone. Note that if more power is trying to go through a pipe than it can handle, a bottleneck will form and the energy "wire" inside the pipe will become red to indicate it.

Older Versions
Before 3.70, the only Conductive (Kinesis) Pipes were Wooden, Stone and Gold ones.
