Emerald Transport Pipe

The Emerald Transport Pipe is an item in BuildCraft that is an advanced version of the Wooden Transport Pipe (which can take items out of inventories such as chests and cannot connect to themselves) in that it can allow a filter to be applied to limit what it can extract.

Similar to a Wooden Transport Pipe, they must be supplied with MJ (Buildcraft Energy) from an engine. This can be from BuildCraft or any other mod item that can produce MJ. A single redstone engine is perfectly sufficient in most cases

Recipe
The Emerald Transport Pipe can be crafted with two Emeralds and one Glass.
